The Lost Magnetic Property (1930-1950 Pole Piece)

[G_Motion]

The reward for the non magnetizable pole piece is increased to $2500. 

It could have been a manufacturing defect, it didn't need to be highly permeable.  I checked cold rolled steel, mu metal and superpermalloy and find it strange that CRS with P around 1K has the strongest attraction and super A with P 200 times greater the least.  This contradicts the formula P = M*C in text books.  If a material with P > 1 could be moved between poles using less energy than could be harvested from the motion of the poles, overunity would have been achieved. 

The question, where would the energy be coming from?   Anyone seriously considering overunity has to answer that question before starting.  It is well established energy can't be created or destroyed only converted.  The problem is those working on overunity don't know science and those who know science know overunity is impossible, so nothing significant is getting done.

Magnetic fields just like gravitational ones have energy.  When a permeable material is moved into a magnetic field, the field shrinks and gives up energy.  Some in the form of M*V^2 (velocity of the material) some in the form of heat.   When atoms in metals are aligned by magnetic fields, electron free space is reduced. The majority of thermal energy in  conductors is in the velocity of electrons, when electron free space is reduced it increases their velocity (temperature) just as happens in a cylinder when the piston moves up.

The only way a magnetic motor can work is by harvesting some other form of energy.

Of the four ways to harvest thermal energy I'm considering, magnetism is the weakest.  I suspect the best a single stage could convert would be less than a micro watt. If I'm right, high vacuum, frictionless bearings, perfectly balanced and the right materials will be necessary.

It's just aluminum, whats the big deal ?

Aluminum has been used in the flux path of speakers for years,
it is used BECAUSE it will not retain a polarity, and dampens...

Have you looked at Bismuth?  It's easy to get from melting down shotgun shell pellets (in the ones that have changed from lead to bismuth).  Bismuth is diamagnetic and is actually repelled from a magnet instead of attracted to it.  So that may be part of the formula.

Hey G

Was working on a 57 vet that had a bad speaker that we replaced with a more modern one. Im not even sure if the old one was the original.

But it had the framework of the speaker magnet that you show in the pdf. The magnet has a pole piece attached to the magnet, right in the gap as you show, but it is thin, 1/6 of an inch, roughly the thickness of the gap plate.

It took me some time to get the U frame and gap plate separated(welded)

The magnet and the pole piece have what seems to be copper plating on them. 

Havnt separated the mag from the plate yet.
