The magnetic energy detector is suitable for aerospace, aviation, nuclear power, petroleum, exploration, electronics and other industries. The non-soft magnetic DC measuring system is an automatic equipment for testing soft magnetic materials. Point-to-point impact method and continuous scanning method are two standard methods for measuring flexible loop hysteresis loops. It is mainly used to measure the basic magnetization curve and hysteresis loop of soft magnetic materials under static (DC) conditions, and can accurately and automatically measure the static magnetic characteristics parameters such as initial permeability μi, maximum permeability μm, remanent magnetic Jr, saturation magnetic induction intensity Js, coercivity force Hc and hysteresis loss Pu. The system visual operation interface can quickly carry out measurement work.
