Kapanadze and other FE discussion

[stivep]

kind of silly question.
when you disorient magnetic domains in  Fe the mutual magnetic field is gone.
so  it does any form of disorientation of magnetic  domains
Magnetite is interesting from chemistry standpoint but I'm not the Chemist.

kind of silly question.

Wasn't it on this forum that some people argued that the magnetic field exists separately from the magnet ? That is, it should remain, like the smile of a Cheshire cat. 
It was seems me in topic about virtual rotating fields or permanent magnet motors.

Fe3O4 is a magnetically conductive material, but where have you seen a stable permanent magnet composed purely of this material?

"Today there are many materials used in the manufacture of permanent magnets: Alnico, ferrites (ceramics), samarium-cobalt, neodymium-iron-boron, iron-chromium-cobalt and materials in the form of a mixture of magnetic powder and some binding component."

the magnetic field is the result, not the cause. What causes the magnetic field in a permanent magnet science and you and I do not know exactly.

I think it's the orientation of the magnetic domains. We spent energy on this during magnetization. But we dissolved it, and the domains disappeared altogether. Everything turned into chaos. And the energy spent on magnetization turned into heat.

Is it true ?
It close to theme about an explosion of water drop.
