The Lost Magnetic Property (1930-1950 Pole Piece)

[G_Motion]

>Was this something you found in several old speakers or was it just in one?
just one

>Have you tried looking on ebay or other antique sources for old radio's that >might have such a speaker?

Yes but I don't know how to do a wanted ad on EBAY.

>You might also try some of the audiophile forums. 

Tried but no luck yet.

>You might even find an old speaker designer around.

If they knew of the alloy that would be ideal.

Good luck in your search and I'd be interested in what you find.

All I've found so far is current magnetic theory is seriously flawed.

Field theories were invalidated by Michelsonâ€"Morley, why they're still teaching this crap is beyond me.  What works in the microcosm isn't necessarily going to work in the macrocosm!  I am beginning to believe this alloy is the key and it's been deliberately suppressed.

I doubt it was a sintered material. It looked like aluminum but heavier though lighter than steel.

I know there used to be a way to do a 'wanted ad' on ebay but not sure if that is still around as I don't think it got used much.  Besides if you have a want ad there people are likely to think they can ask a lot more for something.  I would just do a search on 'old speaker' or 'vintage speaker'.  I just ran a search for 'old speaker' and got 741 hits.  It might take a while going through them but if you know what you are looking for you might get a nice deal on it.  I go by the belief that if it's not on ebay it probably doesn't exist anymore.  It might take a couple months of daily checking but it seems everything shows up there eventually.

Reward increased to $1000

The reason I'm looking for a sample of this alloy should be obvious to over unity enthusiasts. When materials with permeability greater than one are placed between magnetic objects the force between them increases.

Start looking for this alloy!  As soon as I get a sample I'll have it analyzed and publish the composition.  The reward is increased to $2000.  There were hundreds of radio companies, one of them discovered the alloy and used it to increase the frequency response of their speakers. Old speakers need to be rebuilt to restore old radios, it would be easy to test the pole piece at that time.  Scrap speakers are easy to take apart. Test the pole piece, if it's not attracted to a magnet yet conducts the magnetic field you've got 2K, plus the composition of the alloy needed to make a magnetic motor.

A magnetic motor probably won't be able to harness a lot of energy, but it will prove the concept. The energy comes from heat. Permeability is a vector not a scalar, and so is temperature in permeable objects. The space between atoms in permeable materials is affected by magnetic fields and some of the the thermal energy ends up in the field, that's the energy the magnetic motor harvests.

Good luck

Is this what you are looking for?

"The constant leakage flux from the speaker would affect the scanning beam and distort the picture as well as the colors, etc. The best shielding is a canister or pot-shaped cover made of a high permeability metal called mu metal. It is basically a short circuit to the leakage flux so the flux can't get through the mu metal and radiate into the surrounding air. What happens is that the leakage flux tries to magnetize the mu metal, the mu metal generates a magnetic field of its own that resists the leakage flux. All of the magnetism stays within the mu metal so it isn't radiated. The foregoing was a simple explanation of how all magnetic shielding works."
