this is really interesting!

the author talk about the volt to use but not the amp, i mean the watt used for that.

where i can get a cheap freq generator ? for a noob like me :)

I have hundred of neo round magnet (some with hole, some without hole, 3/8" cm x 1/8" and 3/8" x 1")
I made long time ago a motor that i call "spiral motor", was turning without any current 359 degree, i wanted a way to disable the last magnet when the rotor magnet was under the last magnet to lets the rotor continue, but coils over magnet idea was taking to much space on my design,

with this new idea its just a mather of putting 2 wire and epoxy on the last magnet of the rotor, i like the idea!!

for neo magnet, you just need to remove the metal coating where the wire will go? not everywhere?

I would like to speculate a bit (and no doubt get shot at a bit). 

I believe that the resonate frequency of a magnet is actually in the Ultra-violet frequency range (or possibly higher).  I think that the 175-180 khz range is a harmonic that may be partly useful. 

Think about this for a minute.  Blue light is just below the Ultra-violet range on the high end of visible light spectrum.  Infra-red light is on the low end of the light spectrum.  Dr. Moray with his radiant energy machine, said that the light bulbs that he used for a load on his machine, had a blue light to them.  And the electricity had a high frequency to it, making it useless for a standard 60 cycle motor, but he could run resistive devices. 

The Infra-red light converts electrical energy into heat.  So the energy conversion chain starts with magnetism.  When you slow down a magnetic field with a copper coil, you induce electricity.  When electricity is slowed down with a filament bulb, it makes visible light. If you slow down light or electricity to the infra-red range, it changes into heat.  Every step is a reduction in frequency and a coresponding change in the form of energy.  Therefore, I would put magnetic resonance somewhere in the Ultra-violet range, just above the visible light spectrum.

I would imagine that is why we can not see a magnetic field. 

A possible interesting test would be to expose a magnetic field to an Ultra-violet light source.  Just wonder if anything special would occur?

Does this theory make sense to anyone else?

Simply apply a 180khz square wave current directly through the magnet at right angles to the magnetic field. Only a small current is required at a voltage of 12-20Volts.
this implies that the magnet must be conductive ! But most magnets are made of non conductive ceramics.

its very simple, just for fun i made a search on google and find someone with the same idea!

http://peswiki.com/index.php/Directory:Paul_Harry_Sprain_magnet_motor

on mine, i was using attraction, magnet on rotor was attracted by the magnet around the stator, but at the last magnet as well, rotor stuck, with the idea of the high frequency 180k, if that work, that mean just a little pulse to disable the magnet at the end

Well very interesting, My question is this. Does it take more power or the equivalent amount of power to diminish a pm field as it does to power an em field? If so, it's a wash.

I see what you are saying. We do need more information however, we don't know how much current was applied, simply 12-20 volts. I imagine that the current value is critical, probably more so than the conductive epoxy, and magnet shape, etc. We know it has to be a sqare wave, which is an aspect of the current, and I'm thinking the amount of current also has to be dead on, to create these disruptions in the PMs. The current probably has to be able to break the surface of the PM in order to react with the electrons in the magnet. He mentioned heavy sparking on unshielded magnets. This may be the current doing everything it can to find a path since the magnet itself is not conductive. Perhaps drilling a very shallow small diameter hole in the magnet in which to seat your wires with the conductive epoxy would help it to penetrate, then coating the mag with rubber or another epoxy.

I have a feeling what's happening here is a shielding effect being created in the outer most material comprising the magnets, since the current cannot penetrate through the entire magnet, it creates a "shell" of strongly diamagnetic materials around the outside, effectively negating the magnetic field. However, note that it doesn't completely turn it off, the magnet in the tube still floats a bit. This would also explain why the disruption is temporary, because the material becomes saturated (electron spin re-aligns) again by the innermost material of the magnet once the current is turned off.

I have no such testing equipment, unfortunately. Not many people do. Since you have the nice freq. generator, I would hope that you would go and get the square mags, and epoxy, and send an email asking what the current is supposed to be.

If you got your info from JackH who has also claimed to be able to turn off a magnetic field with electricity,we can easily deduce it based on what you have posted and what he has posted.

Hello valveman,

The total basses of my invention is the fact that I have learned how to turn a permanent magnet on/off.  It can be done.

I can take any permanent magnet no mater how big it is or how strong it is and turn it on/off just by using 8 watts of electric power.  This has worked out using 1/2 in. dia. to 3 in. dia. rare earth magnets.  Just 8 watts of electric power no matter how big the magnet is.   The electric valve I invented not only turns a permanent magnet on/off with 8 watts but it also amplifys the permanent magnets power by four times.

These valves were used in the overunity motor that is running at over 500% efficiency.

Latter,,,,JackH


8W/12V = .66A
8W/20V = .4A

So somewhere in that range. (if you got your info from JackH)

Ferrite is an iron based magnet(fe). So that may yield interesting results. However the author is indicating that it IS possible to do it with other types, so it probably has nothing to do with the conductivity. NdFeBs are composed of Nickel and Iron mostly so those are probably pretty conductive as well. Also you can get neos without the metal coating, some come with a black epoxy or rubber, which would be easy to remove a small amount for contact points) coating as well. I'll see if I can find some.

This was very interesting too...  Perhaps iron wire would be useful here???

Joel:  This morning before going to work I spent a little time and wound a 200 turn coil on the 3 inch long permanent magnet (alnico 8) and placed this coil inside of the larger coil (same as the coil I gave you). When this permanent magnet core coil is driven with my signal generator (.5 V output) at exactly 174.9 KHZ the output coil will light up a neon tube. If you get off this freq nothing will pass through the transformer for the permanent magnetic field cannot be overcome by the "feeble" input. Need some more investigation here. My intent is to drive the input coil at a freq that will cause a difference (beat) freq of 60 HZ between the input freq and the ferromagnetic natural resonance freq. More later.   ~  Norm

We can use the same metal coating, just cuting the coating where it is not necesary to isolate the plates, then using normal epoxy to prevent magnet to brake.

http://www.kjmagnetics.com/proddetail.asp?prod=DC2E , already have epoxy covering.

I think the B666BR rubber coated block magnet on this page http://www.kjmagnetics.com/products.asp?cat=11 would be better as it's shape would be easier to work with, also rubber would be easier to remove than the black epoxy (as long as there is no nickel covering underneath the rubber). I think that although conductivity has little to do with it, surface conductivity could hinder the process as it would hinder penetration of the current into the magnet, instead causing to arc around the surface.

This was very interesting. The 174.926 Hz freq being nailed down is of particular interest, of course, especially since the author made mention of the MRA in his descriptions. Their application is quite different of course. I was also particularly interested in the fact that adding more magnets of different configuration/type increased the freq by exactly one octave to 349.xxx. The freq is additive based on the number of magnets, but gives no regard to the strength of the magnet, which lends credence to JackH's findings.

I wish I had some equipment to test this. I'd be buying one of those magnets and some conductive epoxy on the way home, and working this out. I'd try pumping 8W @ 12V @ 174.926Hz on a square wave into that mag to see what happens.

Very intersting topic !
Finally a very good idea, how to turn on / off a permanent magnet !

The easiest thing would be to use an iron wire and wind a big coil around
a cylindrical magnet with it. This iron coil would work like a iron core and
would get a magnet itsself from the flux of the permanent magnet.
Also it would
shortout the magnet flux from the magnet back to the magnet
in a loop.
Now imagine pulsing this iron coil with 180 Khz thus making this
coil core non-magnetic, and put a few copper coils around the
unit.. So if you switch on the 180 Khz burst, the copper coils
would get induction and if you switch off the 180 Khz burst,
the copper coils don?t get any induction.
This would get us a solid state free energy device, if the
power needed for the iron core coil 180 Khz burst would be less than the
output power of all the copper coils !
This way also nonconductive ferrite magnets could be used !

Maybe this is also the way the method of JackH is working ?

Regards, Stefan.

Stefan, Liberty should have put that in quotes. It wasn't him that ran that experiment, It's a quote from the link he put in his post. I would recommend reading the whole page, it's very interesting.

Your idea for pulsing a coil by turning on/off a magnet is exactly what I was thinking. When you turn off the current and hence turn the magnet back on, the flux would cause induction, which would cause current flow, for energy reclamation. This could be done in addition to turning a rotor. The possiblities are practically endless. I wish I had access to a freq. gen.

Tao, are you planning on running more experiments on this?

Hi Hartiberlin,

I was just pointing out a discussion between Joel and Norm on a web page that I found where they are trying to derive power from a magnet using a beat frequency of around 174.94 KHZ.  I thought that your readers would find it interesting to read about, because it seemed to add to the discussion topic with information about some tests that some guys were doing using two coils and a magnet with a beat frequency.
Sorry no schematics.  But there is a pretty good discussion of what they were doing with a magnet and dual coil setup using 174.94 KHZ to use as a beat freq. with the magnetic field.  It is not clear to me whether the voltage was a result of a transformer stepping up the input frequency or whether it was actually an output voltage from the magnetic field beat together with the magnetic frequency.  They talked as if it were an output voltage as a result of using the beat frequency on the magnet.  

That is about all I know to pass on.  It is a pretty long read, but some of it is interesting to read about the tests using 175KHZ to 180KHZ with a magnetic field.

I would recommend reading the whole page, it's very interesting.
I did this some time ago. Interesting indeed, but in the end the O/U has been nailed down to a flawed measurement and power calculation.

The 17x kHz are probably just a coincidence that results from the L/C values of the used transducer and coil. Before drawing any conclusions one must know the permeability of the used magnet. Then you can calculate the resonant frequency of the circuit. If this values are at hand, and a dramatic mismatch remains between the f0 in magnetized and unmagnetized state that can not be explained by conventional physics, it is worth to figure out why.

I agree the effect in and of itself is very important, in and of itself regardless of OU. However, even if in their experiments, they did not acheive OU, there are other ways the on/off effect can be used. Not to mention, they were seeing other effects as well, lasting weight loss, etc.

    OK all, just purchased a good signal gen as I had a need anyhow. I coudn't get any conductive epoxy tho. My reasoning here was that if I use a piece of copper flashing on each side, it would replicate what the conductive epoxy would do anyhow. Not to be the case I guess. No matter what frequency square sawtooth or sine up to 2 mhz I used the floating arm above the target magnet stayed the same.
   Considering the discussion I came up with the idea that 12v at 8 watts would need a transistor in the line and use the gen to turn it on and off. Short of winding a coil that could draw the said amount of power, I cant see any other way to retard the magnetic force.
   I will still try for using conductive epoxy yet. Just have to find out where it can be found.

Why electrically conductive epoxy?
Then, the magnet inside two metalic parallel plates (inside a capacitor) is not the same effect?

Post by: mitch on June 16, 2006, 09:26:37 PM
This thought came to me (lonely thing it is)...

Rather than glue on wires with conducting adhesive, has anyone attempted to use a plated Neo magnet, and grind off the plating between the ends where wires are soldered onto the plating?

Ah! Another thought (where there's one, there's ususally more)

If the magnetic flux cancellation is induced by capacitive coupling, then a flat disk magnet, with the side plating ground off, would show less coupling energy to induce the effect than a long narrow magnet.

I am curious if any can measure the A.C. current involved when coupled, which would show a dip/peak when the frequency sweeps into and out of the coupling frequencies.

This could essentially be a magnetic domain resonance, like an NMR coupling, but with magnetic domains rather than atomic nuclei.  The coupling frequency matches the domain flipping time.  If the effect is domain related then fine-grained versed course grained ferrous domain material may show different resonant frequencies.

The magnet material volume would be another good bit of data to compare in a series of tests, to see if it is realted proportionaly somehow to volume.

You cannot solder a neomag without damaging it's strength. direct heat = bad

I think using an iron wire coil around a magnet would be the easiest thing as you could use
very fine isolated garden wire, so the current would be low and just try to
toggle on/off the magnetic properties in this core-coil !
This way also the magnet will not be weakened !

Hi Tao,

This topic is immensely interesting and I would like to do a thorough investigation of the idea. Right now, I am working at my university in the physics department but as an Engineering student, I have access to pretty much whatever I need to do any testing so I want to setup a thorough experiment to prove once and for all if this does work. I want to start with ferrite magnets since the person said they worked well, but I'm trying to understand how to best attach the wires to the magnet. Do I simply touch the tips of the wire to the sides or is the conductive epoxy necessary to make a decent electrical connection... and as one person already mentioned, I wonder how this will effect ceramic magnets since they are already non-conductive.

Is there any way I could get in contact with the original person to ask him about this?

God Bless,
Jason O

P.S. I?ll also try Stefan?s idea with the iron wire also.
Title: Re: Permanent Magnet: ON/OFF Mechanism...
Post by: hartiberlin on June 17, 2006, 02:51:47 AM
Hi Jason,
ceramic magnets will probably not work as they are
nonconductive.
I also don?t think, that glueing conductive epoxy plates will
have any effect on the magnet when being driven by about 180 Khz,
as it would be, like placing the magnet into a capacitor...
Okay, maybe, if you apply 5000 Volts AC peak to peak, but not
at 12 Volts AC peak to peak.....

I guess it really needs a current through a metal,so only
conductive iron based magnets like Cobalt-Nickel-Iron magnets
will work or also only steel magnets which have not a very
big coercitive force ( low Hc)...
So I guess it would be much easier to try it first with
an iron coil around a magnet, as you don?t need to change
the magnet and can see, how the about 180 Khz AC current reacts to the magnetic
properties of the iron wire.

Also you will discover probably, that you can conduct
heat from the ohmic currentheating of the iron wires into the direction of your magnet field.

This I had discovered last year, when I played shortly with an iron wire coil.
As the magnet field from the permanent magnet is "sucked" into the iron coil,
the heat generated by the ohmic heating of the iron wire is flowing
into the direction the magnetic field from the permanent magnet goes through the coil.
So the heat is maximum there, where the most flux is squeezed in the iron coil...

Also, maybe you can confirm, that iron wire coils don?t have much
Back EMF when driven with pulse waveforms.

There are still many new discoveries to make with iron coils.

If you have access to all the necessary equipment, just do it as outlined in the original post first. Don't change any of the variables. If that doesn't work, then go ahead and experiment with coils and iron wire etc. There are a lot of projects that have been declared not to work after half a dozen experimenters failed to even conduct their experiments to spec.  They immediately start modifying...

@kadora,
what exactly did you test ?
If you pulse the coil with square waves you will see no
Back EMF pulses coming from the coil, what a normal copper coil would do.
I guess this is because at lower current values the magnetic field is still completely
inside the iron of the coil. Maybe only higher currents will drive the magnet
field out of the iron wire..and then we would finally have Back EMF, when switching
off the current...
Or do you have another explanation ?

Yes, he didn't pump enough power into it.

Without knowing his set up, or what he meant by "it didn't work" all we can assume is that it did nothing. Not working could mean that it only moved a small amount, or whatever.

At any rate, as tao said in an earlier thread, the resistance in iron wire is about 10 times greater than copper wire. Think about what that does to inductance.

nuff said.

My magnetic valve does not use energy pulses, just plain old dc from a 6 volt dc latern battery(8 watts).   In fact it can also be done mechanically.

One day as soon as I get the patents back I will tell all.  Should be soon.

So you change the direcetion of the electron spin precession ( magnetic moment ) by AC current.?
This discussion is a bit out of my topics,but there is so called spin valve systems,where magnets resistance is changed by external magnetic field.
http://www.ifw-dresden.de/iff/12/magneto/spinvalve.html
I wonder,if this kind of spin valve system can work in reversed mode,so that you can change magnetic domains direction by AC current?I have no time to think this deeply,but this is interesting topic anyway.

Hi Jack,

I'm not knocking the idea, I'm trying to understand why it doesn't effect your switched magnets.

That's rite, JackH.
Here's parts of one of projects.
After a while this tiny, but powerful neodium magnet (in the middle) created a 'hole' in ceramic ring magnet (marked yellow, reversed polarity), which easily can be located by other ceramic magnet.
As well bad for magnets is heat and vibration, 'abuse', like Jack said.

Hello longwolf,

""I've de-magnitized tools by exposing them to an alternating current""

I don't know, but maybe that is why you never see permanent magnets in an ac motor.    Yes ac will de-magnitize a permanet magnet, that is called abuse to the magnet.
Could be :)

Quote
Can you answer me one thing?  How can a permanent magnet last in a DC motor for so long?   Maybe because it is pulse DC and never goes totally against the permanent magnets poles.
I'm not sure, but as long as the applied field only attracted the magnets, there wouldn't be a problem as it would keep the magnetic domains aligned.

Quote
One thing you may want to know.  You can put a pare of permanent magnets along side of each other, in reverse polarity.  The magnets will still never go dead as long as both magnets contain the same power and you don't hammer on them.
I don't remember where I read it, but there's as site that sells neos.
They have a page about caring for magnets and it warned against storing them with like poles facing each other.
Which would also explain why PMM's that work on repulsion tend to kill the magnets.
(Perhaps those motors had vibration problems, as you mentioned)

Of course you're the man with a working proto type of the switch and if it isn't degaussing your magnets, then that's terrific!
Can't wait to learn more about it :)

Hi Esa,

You mention the 180kHz frequency. I would like to know why just around this frequency value happens something with permanent magnets?  Isn't there a even higher and better frequency like that because I can imagine any change in spin direction or similar effects in the magnets by exciting them in the higher GHz range? The 180kHz is way too low subharmonic in my mind.
Could you refer to some papers on the effects of the 180kHz frequency or similar frequencies on permanent magnets?
Or any other interesting info with respect to this?

Of course other people's opinion are also welcome.

Thanks

On the first post that initiated the current topic, one specification to replicate the magnet ON/OFF phenomenon is:

Quote
Then connect these wires to a simple square wave generator circuit, capable of going up to 250khz.

Quote
Field dimishes on both poles. Square waves is AC with no DC offset. (A sine wave doesn?t do anything). The square wave needs to have a sharp leading edge.

One square wave of  frequency equal to Fo, is one sine wave of frequency Fo (called the Fundamental component) plus many lowest amplitude sine waves at multiple of Fo frequencies (called the Harmonic components).
For example, the following animation is one square wave synthesized by the sum of one fundamental sine wave plus 24 harmonic sine waves:

http://upload.wikimedia.org/wikipedia/commons/thumb/0/0a/Synthesis_square.gif/350px-Synthesis_square.gif

For one square wave with fastest rising and falling edges (shortest rise and fall time) but same amplitude and frequency parameters, the harmonic components will have highest amplitude and more harmonic components of highest frequencies is required while the fundamental remains unchanged.

From previous analysis:   
If to use a square waweform is too important then his rise time is important.
If there are a phenomenon, as some kind of resonance at Fo frequency, then a pure sine wave should produce the same effect than either one square wave of same Fo frequency, or than one square wave of lowest frequency such that Fo is multiple. (square wave of frecuency equal to Fo/N wherein N is a natural number).

I want say that if the phenomenon is produced by resonance at a highest frequency that 180 KHz (N x 180 KHz) and the square wave has low rise time then not effect because the harmonic component of frequency N x 180 KHz that excites the resonance is too weak or does not exist. Also this explains why a 180 KHz sine waveform doesn?t do anything and why the square wave needs to have a sharp leading edge.

In fact a known resonance phenomenon in ferromagnetic materials that serves as technique to probe the magnetic moment occurs at UHF frequencies:

Hello everyone,

Now where has this great thread been hiding, lol. What a major breakthrough this would be.  I'll have to think about this idea and see what comes up.


Hi

I totaly agree with Hartiberlin - behaviour of coil
wound with iron wire is strange .
For example I produced a selenoid wound by iron wire
and this selenoid did not work . It surprised me.
Does somebody a theory why it is not working?

thanks


@kadora,
what exactly did you test ?
If you pulse the coil with square waves you will see no
Back EMF pulses coming from the coil, what a normal copper coil would do.
I guess this is because at lower current values the magnetic field is still completely
inside the iron of the coil. Maybe only higher currents will drive the magnet
field out of the iron wire
..and then we would finally have Back EMF, when switching
off the current...
Or do you have another explanation ?

If the current reaches a certain point then the iron (iron wire) saturates. There are still fields inside the iron wire after saturation, but the addition of fields from the current continue beyond the wire.  When this occurs the iron wire contains no appreciable inductance. Below this current point the iron wire by itself has appreciable inductance.  This is easily demonstrated with FEMM so long as you make sure your FEMM magnetic iron properties has saturation level just like real life. For the most part I have to add a few BH points to the FEMM magnetic properties to simulate real saturation effect in materials.

Tao, thanks for posting all your information. If it's true, and we have no reason to believe it's not, then it's priceless!

This maybe of interest.
Magnetic shielding, well it's more in line with tipping the "neutral plane" between two opposing and equall magnetic fields apparently using a much lower force than the resulting imbalance. Note the fliping of the poles right at the "neutral zone".
The principle is simple, and makes sense.

It could be fairly easy to build, if one has the basic materials and few simple tools.

Post by: PaulLowrance on September 12, 2006, 10:23:30 PM
I know there are various levels of resonance in magnetic materials, but was not aware of any standard set frequency. I know iron atoms typically flip at around a few ns, which would give a few hundred MHz resonance. On a larger scale we have avalanche effects, which are much slower and typically anywhere from a few ms to ns.  Also we know that all magnetic materials are internally saturated or near saturation due to domains. So it is very possible there's an atomic magnet resonance (AMR) akin to NMR (Nuclear Magnetic Resonance). 180 KHz doesn't sound unreasonable for such a resonance, but this would probably very between ferromagnetic based atoms such as iron or manganese or cobalt. Perhaps Iron based materials resonate at 180 KHz and Nickel based materials at perhaps a higher frequency.

If this is true then I sure would not want to put my hand near material where the entire magnetic is resonating. Not that it would be dangerous to look at but a good size chunk sure would generate a lot of voltage. I don't know why a square wave would be required except square waves apply more force is all.

Tao mentioned something very interesting about dielectrics. It's possible certain epoxies or even PM's have high dielectric, which could cause a strong E-field. Has anyone heard of E-fields affecting magnetic material. I think it requires extremely intense E-fields. That would be cool though and everyone's dream.

I think this is an inductor inside a cap somewhat similar to a parallel RLC except there's also an additional cap in series with the L. We know that parallel LC has high resistance and requires low current from power source, but within the LC loop there is a lot of current. So obviously if we found the resonance and given high enough voltage there would be enough current cause the domains to form a loop around the magnet, which would of course cause the magnet to not work. It would be more difficult with NdFeB magnets because of their extremely high coercively. Something like Alnico would be great. I just can't see this working on ceramics because of their high electrical resistance.

I think if you keep trying you'll find the correct setup. I don't think it's a "free energy" source though. It probably would not consume too much current but I think 10 volts is a little to low, especially for NdFeB. May be 20+ volts and Alnico magnets.

tao, I think you have it. Just use a dual power source op-amp and some good mosfets, perhaps IRF540's. I had such a circuit, but I lost my HD last month. Here's a good 50% duty cycle 555 timer:

Title: Re: Permanent Magnet: ON/OFF Mechanism...
Post by: Esa Maunu on September 13, 2006, 01:40:32 PM
This ON/OFF mechanism can be caused by the magnetic field that is crated by current flow through the magnet.
The magnetic field, created by current flow, is on 90 degrees with the direction of the current flow through the magnet, so it has a same  direction as there is in a permanent magnet. If the created magnetic pole by current flow is opposite with the permanent magnets pole, they cancel each other. Also,there is a possibility that magnetic flux lines are canceled out by cutting the magnetic field by sharp DC pulses.

Opposing magnetic fields have a tendency to cancel each other.
But it is most likely that this effect occurs because of  sharp edges of the current pulses.Anyway it is clear that the frequency of the pulses must be high.

We're assuming it only works at 180 KHz. I suspect it can vary to some degree, especially if the PM is very thin compared to length. Was it Liberty who posted link to similar work that mentioned 170 to 175 KHz?  This theory works nice so far. If you double the width of the PM (doubling L) then C cuts in half. We know resonance is:

F = 1/(2pi sqrt(LC))

If L doubles and C halves then we still have the same frequency. :)

Seeing the first post in this thread has been removed I decided to have a hunt around and I think it went along these lines below:

**Quoted from another source**

on/off switch for permanent magnet

Ever considered whether it?s possible to turn a *permanent* magnet on/off at will ?

Well now you can, and those who are astute enough will realise how this can be used in motors, generators etc.

How is it done ? Simply apply a 180khz square wave current directly through the magnet at right angles to the magnetic field. Only a small current is required at a voltage of 12-20Volts.

Take a magnet, and ensure any protective metal coating is removed (e.g. most neodymiums have a metal layer over them). Then connect two wires, one to either side of the magnet at right angle to the direction of the magnetic field. Use conductive epoxy to do this. Then cover the whole magnet in an epoxy layer.

Then connect these wires to a simple square wave generator circuit, capable of going up to 250khz. At around 180khz you?ll notice the power of the magnet significantly reduced (to virtually zero).

An easy way to view this is to place another magnet in a tube, in such a way that it cannot rotate. With the other magnet with the wires attached oriented with North up. And the magnet in the tube oriented North DOWN. Place the tube on top of the other magnet. Thus the magnets repel.

As the tune your circuit up to 180khz you?ll be able to the see the repelled magnet lowering as the magnetic field diminishes. Switch off the current and the magnet in the tube leaps back up as it is repelled once again. The strength of the magnet does not appear to deteriorate even over many thousands of cycles.

Note I?m talking about a CURRENT being applied through the magnet NOT another magnetic field being applied at right angles using a coil or such like.

I have come across some information that, if true, would certainly make everyone's dreams come true. I was initially holding back this info so that I could test it out myself first to see if it is viable, but I lacked some of the key ingredients in the 'process'.

The originator of this information had this to say:

Quote
Ever considered whether it?s possible to turn a *permanent* magnet on/off at will ?

Well now you can, and those who are astute enough will realise how this can be used in motors, generators etc.

How is it done ? Simply apply a 180khz square wave current directly through the magnet at right angles to the magnetic field. Only a small current is required at a voltage of 12-20Volts.

Take a magnet, and ensure any protective metal coating is removed (e.g. most neodymiums have a metal layer over them). Then connect two wires, one to either side of the magnet at right angle to the direction of the magnetic field. Use conductive epoxy to do this. Then cover the whole magnet in an epoxy layer.

Then connect these wires to a simple square wave generator circuit, capable of going up to 250khz. At around 180khz you?ll notice the power of the magnet significantly reduced (to virtually zero).

An easy way to view this is to place another magnet in a tube, in such a way that it cannot rotate. With the other magnet with the wires attached oriented with North up. And the magnet in the tube oriented North DOWN. Place the tube on top of the other magnet. Thus the magnets repel.

As the tune your circuit up to 180khz you?ll be able to the see the repelled magnet lowering as the magnetic field diminishes. Switch off the current and the magnet in the tube leaps back up as it is repelled once again. The strength of the magnet does not appear to deteriorate even over many thousands of cycles.

Note I?m talking about a CURRENT being applied through the magnet NOT another magnetic field being applied at right angles using a coil or such like.

The applications are:

A motor using only permanent magnets and no coils. As it?s the coils that take all the energy in a conventional motor, you now have the basis for a self running motor. As the switching current is minimal and at a low voltage the watts required for the switching is minimal and could generated by a few generating coils around the motor itself.

In other words a motor than can run for free.

At 180khz a resonance effect takes effect at the spin level of the electron, it?s the original alignment of the spin that causes the magnetic field in the first place. At 180khz a perculiar effect take place which disrupts the alignment of the spin and causes waves of alignments (in x,y,z planes) to occur. It?s the waves of alignment which causes the magnetic field to be disrupted.

Now, before you write this off as not possible, consider these facts:
1. Wootan, with the MRA, felt that magnet resonated at around 175KHz.
2. Hans Cooler also said that magnets' resonant frequency was around 180KHz.
3. The originator of this information had these other things to say which sure seem like he did in fact do what is said above:


Quote
Yes it does work on circular magnets but the placement of the wire is more crucial as they have to be exactly opposite each other. (i.e. a line drawn through where the wire attach must go through the center of the magnet.)

It doesn?t work on magnets with a hole in the center.
AND
Quote
Yes tesla was looking at collapsing magnetic fields. I also beleive this is why Tesla choose 60Hz as the frequency for electric power distribution, being a divisor of 180Khz.

The jag principle is not the same. They rely on collapsing the magnet field using another magnetic field.

The problem in generating a motor using the outlined method are the unusual static effects that occur. (I use the term static loosely here). Unless the magnets are covered in epoxy, massive sparking occurs from stator magnet to rotor magnet. I have no idea why this happens, but also massive voltages get built up on anything metal that is nearby - by which I mean if you touch them you get a nasty jolt.
AND
Quote
Got to go now. Just give it a try. Ferrite magnets work very well and are easy to attach wires to. Neodymium are much harder as once you remove the outer metal they tend to disintegrate very easily.
AND
Quote
Field dimishes on both poles. Square waves is AC with no DC offset. (A sine wave doesn?t do anything). The square wave needs to have a sharp leading edge.


It is interesting to note his statements about the static effects produced by the magnet's interactions when the magnet is turned off and on near another magnet. This is similar to the "radiant effect" of Lindemann/Tesla/Gray and the charging of nearby metalic objects!

All the evidence above makes me believe that this gentlemen is telling the truth and made the devices described above.



So, I put this out there for all of overunity.com to see and test.

This is a VERY easy setup to test, I recommend using uncoated rectangular/square ferrite magnets and using ELECTRICALLY conductive epoxy on the sides of the magnet, PERPENDICULAR/RIGHT_ANGLE to the magnetic field.

I feel that this WILL work because it makes perfect sense and the author/originator seems to really have done what he said he did.

I look forward to your replications!

If anyone needs to see a picture to better visualize I would be glad to make one!

EE Times:
Magnetic domains switched from 'hard' to erasable

R. Colin Johnson    
EE Times
(08/13/2007 9:00 AM EDT)

Perpendicular magnetic recordings can now be switched from hard (permanent) to soft (erasable) by way of a discovery recently made at the University College London. Using a designer material with strong anisotropy, the researchers demon- strated how to switch magnetic domains from permanent to erasable by applying a longitudinal magnetic field to modulate the domain walls' strength.

"Our idea for changing a magnet from hard to soft involves applying a small magnetic field orthogonally to the preferred direction for the magnetization," said Gabriel Aeppli, director of the university's London Centre for Nanotechnology. "The magnetic field can be used to modulate the strength of the domain wall pinning, which is what determines whether we have a hard or a soft magnet."

Using an orthogonal magnet to switch a perpendicular domain wall from hard/ permanent to soft/erasable can only be performed with certain magnetic formulae with strong anisotropy, such as those used for perpendicular hard-disk media, Aeppli said. "In a disk drive, we talk about 'perpendicular' recording media, where the magnetization is perpendicular to the plane of the disk," he noted.

The London Centre for Nanotechnology currently is protecting its intellectual property rights regarding perpen- dicular recording in disk-drive media, and consequently it is keeping the details of Aeppli's discovery as it applies to hard-disk media a trade secret. But Aeppli said engineers will find many other uses for switching magnetics' domain-wall strength. "Our discovery will enable transformer cores with tunable inductances, and permanent magnets whose ability to hold objects can be switched on and off," he said.

Aeppli's research group released photographs of ferromagnet domain-wall patterns spaced just 100 nanometers apart, showing how the walls could be moved by changing the force with which they are pinned. First the magnetic domain was that of a hard, permanent magnet with strong pinning. After switching, domain walls exhibited the soft pinning of an erasable magnetic domain.

Aeppli led an international team of scientists, including U.S. members at the University of Chicago, who together contributed to the discovery that magnetic domains can be switched by subjecting them to an orthogonal magnetic field. The scientists demonstrated that magnetic domains could be tuned through a continuous range--from completely hard to completely soft--at low temperatures. Now the group is attempting to extend its work by demonstrating the same tunability at higher temperatures.

The group is also experimenting with doping ferromagnetic materials with impurities to alter their magnetic properties, similar to the way semiconductors are doped to tune their electrical properties. Thus far, even trace amounts of impurities have been demonstrated to have a huge effect on the magnetic properties of ferromagnetic materials with strong anisotropy.

Of all the various theories and approaches I've read here in my short membership, this is the first one that may actually cause me to actually hit the workbench, or at least the phone.  Thanks for pointing out this article, Stefan. 

"..."Our discovery will enable transformer cores with tunable inductances, and permanent magnets whose ability to hold objects can be switched on and off,"..he said"...hmmm...I said.  You'd think that he, as the expert on this, might also realize (unless we are misunderstanding or it takes lots of power to do this) the MEG and PM motor aspects and possible free energy applications. 

It sounds like they are only interested in protecting the info-store applications which is very unusual if the kinds of things going through our minds right now also went through his!  I'm gonna try to get ahold of this guy and see if he's got anything he can publish.  Who knows, maybe this is the big breakthrough and he knows it and realizes it is so big he could never protect it?  Maybe he'll open-source it for all applications except data storage?  Jeeezzz...dammit....I'm starting to sound like a believer.  I better take a pill or something.

Seriously, Gaby, to wander into your baited web, here is how I would explain your disclosure, which I had viewed once prior:

Gaby puts a strip of ferrous metal flat against one pole of a permanent magnet and discovers that a magnetic field now extends into the ferrous metal and he can pick things up with the far end of it. 

Then Gaby places an identical second magnet exactly symmetrically and opposed in polarity on the other side of the strip of metal.  He now discovers that the two exactly identical yet opposing magnets no longer exert a strongly polarized field permeating to the far end of the metal strip. 

This is a profound enough discovery for Gaby to write up a formal-sounding legal disclosure, claim it as an invention and draw nice diagrams so that the lesser brains in the world will be able to reproduce his amazing discovery that opposing superimposed identical fields tend to cancel each other.

Is there some deeper, more interesting, more subtle lesson or principal I have glossed over in this analysis, Gaby?  I just know there must be but, as you can see, I am far too stupid to see it or to ever understand it.  Sad, isn't it?   :(

I slighty disagree: it states something.
Whether or not it can be disapproved, keep reading and decide for yourself:

Well, this morning I went to make my coffee but I forgot to switch the cooking machine on. Then, I remembered the ?lead-out? theory and I told about it to the cold water. Hear it is: ?dear water, there are billions of molecules in you, all colliding without any loses and all submerged in gravitational field. I don?t care about what you?re doing there, but according to the ?lead-out? theory, you should lead-out gravitational energy and start boiling at once.? Guess what? It started to boil. No I had a real situation. It wouldn?t get cold. In fact it wouldn?t stop boiling!!! Gee, how will I drink my coffee?!! But that?s nothing: the cooking machine, hearing the story from the boiling water, although switched off, started to get warmer and warmer. It finally melted down. Then the whole kitchen. Then my house and then the entire neighborhood. How do I stop it?!!!
Someone has to stop the story; otherwise the whole surface of the Earth will be melted down due to the huge gravitational energy being led out.

Hope you like the story,
Tinu

This is the point the publication was aiming for. "Additional fields may decrease the flux.", there is no need to soften up the whole magnet. :P  If after reading the document the exploitation of the effect is still not jet wholly entirely obvious to you you can still use this new found understanding to understand John Ecklin's work who basically used the same trick in much more complicated more advanced and more useful configurations.

The simplicity of my document may be further appreciated when viewed in it's context (of which I still have to write most of. haha) I have just coded up the science journal's archive queries, like this the context is a bit more obvious.

Gaby,

Good to see you're in fine form as usual.  I guess the bottom line is how do we move the lines of flux around to where we want them without doing more work than the resulting flux changes can provide back for us in a given scheme.  Always the damn piper to pay, it seems. 

At least it seems that way here in "let's build some and (choose one or more...get rich...save the world...become famous...thumb our noses at the establishment)" land!

Side effects could include critical thinking

but it's so boring and anoying to be a knee jerk. Lets get back the the information you are trying to apply your cognitive dishonesty to.

Seeing the first post in this thread has been removed I decided to have a hunt around and I think it went along these lines below:

**Quoted from another source**

on/off switch for permanent magnet

Ever considered whether it?s possible to turn a *permanent* magnet on/off at will ?

Well now you can, and those who are astute enough will realise how this can be used in motors, generators etc.

How is it done ? Simply apply a 180khz square wave current directly through the magnet at right angles to the magnetic field. Only a small current is required at a voltage of 12-20Volts.

Take a magnet, and ensure any protective metal coating is removed (e.g. most neodymiums have a metal layer over them). Then connect two wires, one to either side of the magnet at right angle to the direction of the magnetic field. Use conductive epoxy to do this. Then cover the whole magnet in an epoxy layer.

Then connect these wires to a simple square wave generator circuit, capable of going up to 250khz. At around 180khz you?ll notice the power of the magnet significantly reduced (to virtually zero).

An easy way to view this is to place another magnet in a tube, in such a way that it cannot rotate. With the other magnet with the wires attached oriented with North up. And the magnet in the tube oriented North DOWN. Place the tube on top of the other magnet. Thus the magnets repel.

Not sure how toxic neo?s are, but they are toxic as far as I know.
And I was reading about ?don?t burn them? so
I would want to be careful about any sparking, around a ?bare neo?.
i would not want to handle them without gloves either.

You can handle them with gloves, just don't try to machine them or let them ignite in anyway.

But, handling an uncoated neodynium is totally safe and non toxic, it only becomes toxic when ignited.

I removed the coating of a small Neo I got laying around but the magnet was just as conductive without the coating.
With coating the resistance from side to side was measured to 0R, without the coating the resistance was still 0R.
I don't believe the neo can be turned on/off by a square wave signal.

I also measured a ferrite magnet 4 times as big as the neo.
This resistance was approx 0.5 to 1.5 Megaohm depending on how hard pressure I put on the test pins.
If any magnet can be turned of it's a ferrite magnet.
I might try to do this at work during next week. I got access to a square wave generator capable of 0Hz to 800Khz
and putting out heavy currents as well. The square wave voltage can be adjusted between 5V to 40V.

I have now tested the so called ON/OFF mechanism on a ferrite magnet.
I'm sad to report that I did not notice any weakening of the magnetic field at 180KHz or any other frequency for that matter.
I tried voltages between 5-40V at 1Khz to 2Mhz (I tweaked our generator by swaping capacitors.)
The magnet had conductive tape onto it and I measured the resistance to approx 1Mohm.
Perhaps somebody else is lucky when trying this.  Personally I think the original idea is flawed.
