Magnetic property testing is an essential process for evaluating the quality and performance of soft magnetic materials. By measuring key parameters such as magnetic permeability, coercivity, saturation magnetic induction, core loss, and hysteresis loop characteristics, manufacturers can verify material performance and optimize production quality. This article explains the importance of magnetic testing, the main parameters tested for soft magnetic materials, and the testing requirements for different materials including amorphous magnetic materials, electrical steel, and electromagnetic pure iron.
Soft magnetic materials are essential functional materials widely used in transformers, motors, electronic components, and new energy equipment. This article explains what soft magnetic materials are, including their main types such as amorphous magnetic materials, electrical steel, and electromagnetic pure iron. It also introduces their key properties, including high permeability, low coercivity, low core loss, and their applications in modern electrical and energy industries.
