This may be useful in actually creating something I theorized about a few months ago. I call it a chemomagnet (as opposed to electromagnet).
The basic premise is that individual magnetic domains are free to float and are unorganized until a chemical signal locks them into place in some sort of structure. The energy required to align and bind them would be chemical in nature, and once bound, another chemical signal could be sent to unbind them.
The magnet would be controllable, like an electromagnet, but would not require any electricity at all to operate.
- kybernetikos 7y agoA bit like those heat packs where you click a metal disk inside them and they solidify, releasing heat? You could imagine doing the same but it 'turning on' a 'permanent' magnet.
- GistNoesis 7y agoIsn't a chemomagnet magnet just a scaled down version of a mechanical switchable magnet?
- yetihehe 7y agoYeah, but you could program it with any number and position of magnetic poles. Imagine a ring of this material as a stator in electric motor, you could reprogram it with 4 or 6 poles on the fly.
- dustfinger 7y agoliquid programable motors with possible temporal formation capabilities! Sounds one step closer to Skynet's liquid metal terminator :-) Fascinating!
- cr0sh 7y agoI wonder if your idea - or this "magnetic liquid" - could have application in "artificial muscles"? Fascinating to think about...
