Hi Guys,

I was using real weak craft magnets when I made the movie showing the 2 inch ball turning inside a circular track.  The magnet group angles had to be near perfect to get this to work at all. What the magnet  grouping angles were is unknown to me but the ball stopped turning after a while.

If someone has someone has a bunch of thin rectangular neodymium magnets and trys this they might be surprised what happens. You will have to experiment using different size steel or iron balls for best end of track group rollaway results.  Maybe more than three track magnetic groups??

Mu-metal is a nickel-iron alloy (75% nickel, 15% iron, plus copper and molybdenum) that has very high magnetic permeability. Permeability is represented by μ.
The high permeability makes mu-metal very effective at screening static or low-frequency magnetic fields, which cannot be attenuated by other methods.
Mu-metal requires special heat treatment - annealing in hydrogen atmosphere, which reportedly increases the magnetic permeability about 40 times. The annealing alters the material's crystal structure, aligning the grains and removing some impurities, especially carbon. Mechanical treatment may disrupt the material's grain alignment, leading to a drop in the permeability of the affected areas, which can be restored by repeating the hydrogen annealing step.


[edit] Uses and properties
Mu-metal is used to shield equipment from magnetic fields. For example:

Vacuum chambers for experiments with low-energy electrons, for example photoelectron spectroscopy
Magnetic resonance imaging equipment
The magnetometers used in magnetoencephalography and magnetocardiography
Photomultipliers
Cathode-ray tubes used in analogue oscilloscopes
Superconducting circuits and especially Josephson junction circuits
Electric power transformers, which are built with mu-metal shells to prevent them from affecting nearby circuitry
Magnetic cartridges, which have a mu-metal case to reduce interference when LPs are played back
Hard Drives, which have mu-metal backings to the magnets found in the drive
Other materials with similar magnetic properties are supermalloy, supermumetal, nilomag, sanbold, Molybdenum Permalloy, Sendust, M-1040, Hipernom, HyMu-80, etc.

Is it really necessary to spam the forum with repetitive posts and rather frightening photos?

Is it really necessary to remind any of the people reading this forum that mu-metal has high magnetic permeability?

But perhaps it is necessary to remind someone that this high permeability means it is strongly attracted to magnets, even more strongly than, say, pure iron? This is why it "shields" magnets--because the field lines more easily penetrate the mu-metal than other materials. IF you design your mu-metal box cleverly, as we have seen, it will indeed "shield" the magnet inside it--because, and only because, it "sucks up" all the field from that magnet. However, it will still be attracted to external magnets. You might be able to balance the geometry so that in some areas the fields cancel and you think there's no magnetic force present. But just try to remove the mu-metal, in that case. You will find out differently.

Trying to construct a magnetic perpetual motion motor using magnetic shields has been tried before, many times, mostly on paper. When one attempts to construct a shield motor in real life, the problems become very evident, and the inventors usually move quickly on to other pursuits.

By the way, if you take a piece of mu-metal from, say, a surplus component, and you bend it or machine it or work it in any way, it loses some of its magical mu-permeability and must be re-annealed (or however they get all that mu in there). So most of us might as well be using soft iron; it's a lot cheaper.

@TK

I am putting up a photo of a small standard AC fan motor. The two red arrows are pointing at two copper triple winds that are 180 degrees apart. Would you or anyone else know what these are for to see if such an approach can be used with a magwheel.

They act as "secondaries" to the "primary" formed by the main power coil. There is a large current at low voltage induced in these 3-turn windings. The mag field from that current biases the armature to start turning in one direction.

Of course, that's just a guess, on my part.

Hi Wattsup,

I think such motors are called shaded pole motors.  The thick copper wire constitutes a one turn coil with its ends shorted and the current induced in this one turn coil delays the phase of  the magnetic flux in that part of the pole enough to provide a rotating field.

See this link: http://en.wikipedia.org/wiki/Shaded-pole_motor

PS,  you asked the same question one year ago and I also answered it..., see here:

gyulasun is correct. These copper circuits constitute an AC magnetic phase delay. They help
during startup to get the rotor to rotate in the proper direction. You would not want your clock
or fan running backwards would you?...the motor itself generally can run backwards.

Hi Guys,

I am building this and going to try one of my box magnet rails on the floor to power it in event I cant get the large ring magnet and piston magnet to work. Plan to mount all on a wood sawhorse.

The fellow who posted it said it worked for 3 days until it was destroyed.  Another fellow tried replicating it but Ihe did not make it as illustrated in the video. Notice there is no hand pumping on the bike wheel. Look at the bike wheel "SHADOW" area near the top in his last clip..Right after   "She left me the next morning"      The  setup is self powered.

Hey --LIGHT -- you have some nice powerful magnetic box rails made already. Give it a try.  All you need is two ring magnets and a bike wheel or flywheel , a fiberglass rod, and some fittings.   McMaster - Carr is where I get all my odd parts.  They have an on line catalog.

Hi Guys,

I figure this might be how it should work.

One large ring magnet is laying on the floor. Its not 2 ring magnets as illustrated. My mistake I am now correcting.

The centerpoint of this ring magnet does not have much magnetic energy to resist the gravity fall of the piston magnet. In this case the swing of the offset flywheel forces the piston magnet to the left side and it uptravels.

Tom

 I am having problems with exact timing and it has led me to adding sliding frame work. This drops the magnet on the edge and as it pushes it away,the magnet moves towards the middle drawing the rotation and as it slides over further, it then starts to push after bottom center which then pushes the rotation.

 I still have to make the frame work but the following picture should give you an idea of what I am talking about.

" A SQUARE MAGNETIC RAIL -- ROTOR 360 ROTATION  "

Which is the title of this thread.

Now, I took some flack here for my skepticism and my comparisons of this thread to the famous "RollOn the 20th" thread.

But, I notice several things.

First, there isn't any square magnetic rail with 360 degrees of rotor rotation.

There isn't a square or rectangular SMOT design that works.

The best I've seen is a ball rolling in a circle, but that's clearly rolling on its initial push, not by the magnets.

And now the thread, and the experimenter, is going off in new directions, without finishing any of the old directions or projects.

Yet, no doubt, the originator still believes he has something new and unique.

So, as far as I can see so far, I am right--this is just the same old same old: a person got excited by some magnets and is off on a manic rush, recreating years of research, rather than doing a little reading and study to avoid going over old territory, yet again.

I'll check back in another week. My prediction is that by then, you will have moved on to yet another design variation that has already been tried and rejected by others.

TinselKoala, "There isn't a square or rectangular SMOT design that works."

 I am sorry but you are wrong. they do work but they do not work longer then 1 to 5 minutes and that is one reason we have changed directions. We have not completely done away with thoughts of ways to make it work longer but for now we are working on another project. We do not only communicate here but also by way of emails.

"So, as far as I can see so far, I am right--this is just the same old same old: a person got excited by some magnets and is off on a manic rush, recreating years of research, rather than doing a little reading and study to avoid going over old territory, yet again."

 You are correct but we learn from trial and error and I refuse to except others findings unless every possible way has been tried. Sometimes it's best to do it then it is read about it because by doing it, you could stumble across something that may not have been stumbled across before and every failure leads us to a better understanding.

 Life is a educational experience and the more you experience, the more you learn.

TinselKoala,

Exactly what have you experimented with that worked or did not work?

Name a few things and show me on the internet where I can view them and then I can sit on a fence be a skeptic.

History shows that persons like Tom Edison spent years experimenting before he got the electric light bulb to work. And that is the most simplest device I know of even at todays standard.  The Wright brothers put an airplane in the sky with a human riding it with skeptics watching.

I am a dreamer/ builder and my biggest goal is to in some way make a green machine motor device that does not pollute this world.   I dont care if others using the information here accomplish this ahead of me. I will applaud their efforts.  What I post is given free to the world and not ment to be hidden by some self serving patent.

My only hope is anyone who is successful will donate "ALL" profits recieved  to some charity as I definitely will.  Such as the St. Judes Childrens hospital.  I am NOT into this for money or fame at all.

I am a retired 30 year +  commercial aircraft technician who has seen and worked on most piston, and jet engines. I hope only to be instrumental in seeing a powerful GREEN machine come into play before I leave this world.

Tom
