Five main magnetic properties of soft magnetic materials

Soft magnetic materials are versatile and versatile, with five main magnetic properties: (1) High magnetic permeability. Magnetic permeability (symbol μ) is a measure of magnetic field sensitivity; (2) Low coercive force Hc shows that magnetic materials are susceptible to magnetization by an applied magnetic field, are easily demagnetized by an applied magnetic field or other factors, and have low magnetic losses; (3) High saturation magnetic flux density Bs and high saturation magnetization Ms. This makes it easier to obtain a high permeability μ and a low coercive force Hc, and it is also possible to increase the magnetic energy density; (4) Low magnetic loss and electrical loss. This requires low coercive force Hc and high resistivity; (5) high stability, which requires the above-mentioned soft magnetic properties for high stability of temperature and vibration and other environmental factors.
