Classification of magnetic materials
A ferromagnetic material having a ferromagnetic order, and a broad range of weakly magnetic and antiferromagnetic materials that can be applied to its magnetic and magnetic effects. Magnetism is one of the basic properties of matter. Matter can be divided into diamagnetic, paramagnetic, ferromagnetic, antiferromagnetic and ferrimagnetic substances in terms of their internal structure and their properties in an external magnetic field.
Ferromagnetism and ferrimagnetic substances are ferromagnetic substances, diamagnetic and paramagnetic substances are weak magnetic substances. Magnetic material is divided into two kinds of metal and nonmetal according to its properties. The former mainly include electrical steel, nickel base alloy and rare earth alloy, etc. the latter is mainly ferrite material. It is divided into soft magnetic material, permanent magnetic material and functional magnetic material according to its use. Functional magnetic materials are mainly magnetostrictive materials, magnetic recording materials, magnetic materials, magnetic materials, magnetic materials, magnetic materials and magnetic rotary thin film materials, reflecting the basic magnetic properties of magnetic materials with magnetization curves, hysteresis loop and magnetic loss etc..
