Soft magnetic materials are magnetic materials whose magnetization occurs when HC is less than 1000A / m. Soft magnetic materials are characterized by low coercivity, high permeability, high saturation magnetic induction and minimal eddy current loss. Soft magnetic materials are not only easy to magnetize, but also easy to demagnetize, which can achieve the maximum magnetization with the minimum external magnetic field.
The main function of soft magnetic materials is to transfer and transmit magnetic and electromagnetic energy. Therefore, it is widely used in electrical equipment and radio electronics industry, such as transformer, generator, motor, electromagnet, all kinds of relay and inductor, reactor, sensor core, magnetic shield, magnetic head, magnetic recording medium, computer core, electromagnetic chuck, magnetic sensor (such as magnetocaloric material as switch), etc. Soft magnetic material is one of the important magnetic materials in aerospace, national defense and military industry.
