Negative Inductance and measure of Magnetic force.

I was asked to start this topic by Bob Smith on Energetic Forum. I fell it's better suited for the Overunity web site where the controversy originated.

Thanks for posting this Synchro and of course thanks to Gotoluk for disclosing his experiment. Is it much to ask for a simple circuit drawing? I mean, connections are not very clear. Does it have a secondary?

Regards

@Jag,

The point of the schematic is to demonstrate that the "Inductance of the Coil and Core" decreaase in proportion to the magnet spacing. Therefore; The closer the magnets are to the inductor, the lower the Henrys. The difference in inductance or, the "Negative" amount, is in direct proportion to the inductance it replaces with "Magnetic Force"!! 


Here's a new video on the gain from the "Bucking" poles of the neutralization pulse:

Interesting.. Especially if the associated ratios IN/OUT change their proportional relation by approaching the magnet. Going to test it. Thanks for bringing this in to attention.

ps. not going on to a discussion about saturation and the associated lowering of inductance and increasing of current. I am interested more in braking the proportionality between the values and if this brake exist here. ;)

It would make a difference on how you ran this GAP motor; In attraction or opposition! The neutralization pulse allows a rotor in attraction to pass, while the power coil acts as a pickup coil for the increased output from the re-gaugingt: The rotor increases the output to the "Hybrid Coil" in rest phase.


Here's a short video demonstrating a latching "Reed Switch": Two "Reed Switch's" would be used, one to direct output to storage or looped to source. This kind of motor could run off a capacitor and an interruptor circuit.

Imagine a two magnet mono pole rotor with two reciprocating "Latching Reed Switches" on the axle. The neutralization coil (pictured above) would be connected in series with the switches through a battery and capacitor in parallel. This neutralization attraction motor should run itself with the battery disconnected once started.

The masking coil and magnet attraction delivers less torque to the rotor than the repulsive opposition alternative; The benefit to the neutralization approach is the gain the masking pulse generates in it's own windings from the torsion of it's internal magnetic field forces.


The attraction masking pulse is weaker and otherwise avoided by motor builders. We seek to uncover it's hidden strength!

The commutator circuit needs a diode! The masking pulse is timed to fire at TDC, and carry through to the half way point when it turns off so the attraction can carry it to the opposing rotor magnet. During this time the coil is reconnected to the battery and capacitor through a one way current permiting diode. The charging takes place due to the "Super Position" of the higher coil voltage resulting from the back surge of magnetic force.

Here's a picture of my new build. Notice the ninety degree segment for the reed trigger magnets: Both reed switches have the same origin and destination; The positive electrode of the masking coil and the positive electrode of the power capacitor and battery. The negative lead of the masking coil just connects to the ground of the capacitor and battery.

We can see a 12 volt electro-magnet with a stack of ceramic backing disc magnets on the left in the picture above. This electro-magnet turns into an output coil during the high power phase of the approaching rotor magnet. Not only a higher voltage but an increased amperage show up at the capacitor diode. This ratio of output to input has been measured as over unity by Art porter with his GAP apparatus.

Here's a new video on gauging the "Neutralization Strength" of the electro-magnet on the attraction force of a ceramic block magnet:

This electro-magnet is now suitably balanced for an attraction rotor with two ceramic block magnets for poles with a gap of two coasters in width.

There's a difference between neutralization of opposite polarities and neutralization of attraction. The short video above could be repeated with the holding power generated by the electro-magnet, releasing the ceramic block when the coil power's interrupted. It would waste a lot of power to hold the ceramic block magnet up with power from the electro-magnet, instead of it's permanent backing magnets! 

Art Porter demonstrates neutralization of opposition polarity in his GAP video; The repelling magnets close when the neutralization pulse coil is powered on.   

Compare this to the action of a neutralization motor: The attraction rotor magnet is drawn toward the electro-magnet coil when the coil is in output mode from 90 degrees to TDC. Art's gravity piston of opposition magnets is pushed away from the coil when the coil's de-energized.

The difference is that the attraction rotor builds the output from lowest to highest level; The "Push Away" motion of the opposition magnet has it's charge curve reversed! The attraction motor produces a "Rising" power output curve during the rotor magnet's approach to the coil backing magnets during it's recovery mode.

I'll be comparing input and output from my reed commutator attraction motor soon.

Have a look at this attraction output video first; The volt meter's on the milli volt scale:

Fast forward to 2:30 for the key to the "Orbo" by JLN: "When you apply current to the stator coil, it's only to free the magnets after they have done useful mechanical work"!

The electro magnet has very little reach compared to the backing magnet field. The electro magnet could never run the magnet rotor off current alone because the coil field drops off substantially sooner then the inverse square distance of the PM's.

The electro magnet however, has the power to truncate the PM field completely through it's high perm alloy core, when it's directly attached to them. The placement of the PM backing magnets extends the projected field by a wide margin over what the coil could effect alone.

This solitary fact amounts to a powerful amplification of the electro magnet coil force. The wider field range turns into an asset for the electro magnet as a pickup coil because the rotor magnet begins to influence the coil further from the side.

The core inductance acts like weight in copper for magnetic field strength per unit of electrical input power. We get a greater force field per watt value with higher core inductance. Electro magnets are hardly ever used in electrical motors due to these drawbacks; However, the drawbacks turn to advantages when combined with attraction masking of backing magnets.

The topic of this thread is "Negative Inductance and Magnetic Force". JLN's first Orbo test demonstrates a drop in ferrite toroid coil inductance from 235 micro Henrys to 167 micro Henrys when the magnets are attached to the toroid by attraction. That's nearly a 30% drop in efficiency; That means it will require 30% more current to unlock the magnets.

The "Electro-Magnet", with a high inductance "Samarium-Nickel-Cobalt" core is practically impervious to inductance loss from the attachment of permanent magnets; Thus millions of times more efficient as a masking magnet shunt then the ferrite. The Electro-Magnet's inductance measured 73 milli Henrys with no magnets, and a loss of one mico Henry with the attachment of the backing magnets and an additional one micro Henry loss with the rotor magnet at TDC. That's two "Millionths" of a Henry. That amount of inductance loss is barely noticeable by contrast to the ferrite!

Can anyone believe that the same input power is masking ten times the attraction strength?
