Permanent Magnet: ON/OFF Mechanism...

[tao]

I am recreating the original post to this thread below. I already explained in other threads why I had to remove all my posts. Anyway, for all those wanting the information, here it is.




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:

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:

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

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

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

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

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.

@Stefan

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.

Here's a link direct to the research group website.  The research appeared in detail in the journal Nature on August 2nd and it shows how a magnet can be ?tuned? by subjecting it to a second magnetic field, perpendicular to the original.

hehehe,

I wrote this so long ago already!

Do notice how I didn't use any perpendicular wording.

@Gaby


We name it; you claim it! 

You begin to sound like your friend Lawrence Tseung, who claims his theory underlies and explains every new invention in the field of free energy.  Yet his theory actually states nothing, nor can it be proven or disproven except by Chinese proverbs and charming tales of calm lakes and strong sunshine.  To each his own, I say.

Blind, deaf and dumb as usual, I just don't see the analogy between your "disclosure" there and the subject matter at hand but it is clear that you do and that's okay with me, sir!  My feeble brain is far too crowded and confused to ever understand, I'm sure.

Carry on, oh Sahib, oh Wise and Graceful Master of all the Universe!  We await your next Jewel of Supreme Advance Knowledge of All that Will Be.  Hehehe!
