A magnetic material having low coercivity and high magnetic permeability. Soft magnetic materials are easy to magnetize and easy to demagnetize, and are widely used in electrical equipment and electronic equipment. The most widely used soft magnetic materials are iron-silicon alloys (silicon steel sheets) and various soft ferrites. It has a narrow and steep hysteresis loop, and the magnetization process is close to reversible, with low hysteresis loss, high magnetic permeability and low coercivity. Such as silicon steel sheet, industrial pure iron, pure carbon steel. Such materials have high saturation magnetic flux density, high magnetic permeability, narrow hysteresis loop, small area, small hysteresis loss, small remanence and coercive force.
