The magnetization curve of the magnetic material of magnesy neodymowe

　　Magnetic material of magnesy neodymowe is made of a ferromagnetic material or a ferrimagnetic substance composition, in the external magnetic field H action, there must be corresponding to the magnetization intensity of magnetic induction intensity in M or B, the curve that varies with the intensity of magnetic field H is called the magnetization curve ( M ～H and B～ H curve ).

　　In general, the magnetization curve of magnesy neodymowe is nonlinear, and has two characteristics, magnetic saturation phenomenon and hysteresis. When the magnetic field intensity H is large enough, the magnetization M reaches a certain saturation value Ms, continue to increase H, Ms remains the same; and when the material values of M saturation, the external magnetic field H is reduced to zero, M does not return to zero, but along the MsMr curve. Material working condition is equivalent to the M ～H curve or B～ H curves to a certain point, the point is often referred to as the working point.
