Description
technical field [0001] The invention relates to the field of measuring devices for magnetic materials, in particular to a measuring device and a measuring method for basic hysteresis loops, basic magnetization curves and AC magnetic key parameters of soft magnetic materials. Background technique [0002] Magnetic materials are functional materials that contribute most to scientific and technological progress and economic and social development after World War II after semiconductors. Soft magnetic materials are an important part of the magnetic material industry. The magnetic parameters of soft magnetic materials and their measurement are the key to ensure the quality of the products (mainly electronic products) and to guide the research and development of new materials. [0003] The most basic parameters of magnetic parameters are defined on the hysteresis loop. So the usual magnetic measurement is the mapping of the hysteresis loop. At present, this kind of surveying an...
