Permanent Magnet: ON/OFF Mechanism...

[Esa Maunu]

So you change the direcetion of the electron spin precession ( magnetic moment ) by AC current.?
This discussion is a bit out of my topics,but there is so called spin valve systems,where magnets resistance is changed by external magnetic field.

I wonder,if this kind of spin valve system can work in reversed mode,so that you can change magnetic domains direction by AC current?I have no time to think this deeply,but this is interesting topic anyway.

i think the material needed to block magnetic fields needs to be very well compressed as much as possible in order to take usefull effect in a magnetic field. whatever that material is it needs to be compressed to the max to block magnetic fields.

I don't even dare speculate, I can't imagine any method that would mechanically negate a magnet's field.

I can't wait to start experimenting with this however. Any eta on your patent Jack?

Hello Light,

Yep, it can be done mechanically.  NO electricity at all.

later,,,,jackh

At last... I'm not alone with this opinion.
Thank you, Jack. I hope you get your patents soon!

What prevents this from de-guassing the magnet?
