Magnet performance

Diamagnetic are some categories of substance, when in an external magnetic field, the magnetic field will produce a weak magnetic repulsion phenomenon. Paramagnetic, refers to a material's magnetic state. Some material may be affected by rotary grate magnet field generating means with opposing magnetization characteristic vectors. Such a substance having a positive magnetic susceptibility. And paramagnetic contrast phenomenon is called diamagnetic. Ferromagnetism, refers to a material's magnetic state with spontaneous magnetization. Each samarium magnet material to iron the most widely known.
