Magnetic Separation Cobalt

Magnetism - Wikipedia

The magnetic state (or magnetic phase) of a material depends on temperature and other variables such as pressure and the applied magnetic field. A material may exhibit more than one form of magnetism as these variables change. As with magnetising a magnet, demagnetising a magnet is also possible.
