Explanation
In the external magnetic field H, the ratio of the magnetization M to the magnetic field H, expressed in Z, is a dimensionless quantity in the International System of Units. The value indicates the difficulty of magnetize. The Z of different substances varies greatly, and the influencing factors also vary. Except for ferromagnetic and ferrimagnetism materials, the magnetic susceptibility of other materials is mainly determined by chemical composition. The magnetic susceptibility of ferromagnetic and ferrimagnetism materials is closely related to chemical composition, crystal structure, crystal structure, internal stress, etc., and is a tissue sensitive property.
