So it also called as permanent magnetic materials. For permanent magnetic materials, after magnetized by external magnetic field, they can still keep most of the magnetism even if acted on reversing magnetic field. The requirements for such magnetic materials are high remanence(Br), strong coercive force(Hcb) and high maximum magnetic energy(BHmax).
