Once the external magnetic field is magnetized, it can maintain the magnetism of one or most of the original magnetization directions even under the action of a considerable reverse magnetic field. The requirement for such materials is that the residual magnetic induction strength Br is high, the coercive force BHC(i.e. anti-degaussing ability) is strong, and the magnetic energy product (BH) (i.e. the magnetic field energy provided to space) is large. Compared with soft magnetic materials, it is also called hard magnetic materials
Magnetic materials have strong magnetic materials in magnetic order. In a broad sense, they also include weak magnetic and antiferromagnetic materials that can be applied to their magnetic and magnetic effects. Magnetism is a fundamental property of matter. According to its internal structure and its characters in the external magnetic field, substances can be divided into antimagnetic, paramagnetic, ferromagnetic, antiferromagnetic and ferrous magnetic materials. Ferromagnetic and ferromagnetic materials are strong magnetic materials, anti - magnetic and paramagnetic materials are weak magnetic materials. Magnetic materials are divided into metal and non-metal according to their properties. The former mainly includes electric steel, nickel base alloy and rare earth alloy, while the latter is mainly ferrite material. According to the use of soft magnetic materials, permanent magnetic materials and functional magnetic materials. Functional magnetic materials mainly include magnetostrictive materials, magnetic recording materials, magnetoresistance materials, magnetic bubble materials, magneto-optical materials, magneto-optical materials and magnetic film materials, etc.
