Chameleon Magnets aka Electrically Induced Ferromagnetism…

Magnetism is more than just a fun property to experiment with in Science 101, not just a scientific curiosity. Scientists have discovered the Chameleon Magnet, a permanent magnet that can be switched on and off at will. Magnetism is the glue that holds every atom and molecule together. The very small world of nano magnetism – magnetism of atom’s and molecules – is very a different beast, not high school magnetism. In this world free electrons can be used to pass spin information on to other electrons, large groups of electrons spinning in sync can set up a magnetic field. All of these bizarre effects are being studied and applied to Chameleon Magnets and Spintronics, the science of using the spin of electrons to do work in electronics gadgets.
