Automatic measurement of soft magnetic materials in the static (DC) under the conditions of the basic magnetization curve and hysteresis loop, the accurate measurement of initial permeability I, static magnetic characteristics of maximum permeability m, saturation magnetic induction intensity Bs, the remanence and coercivity of Br Hc and hysteresis loss of Pu parameters. According to the measurement principle of classical shock method, adopt computer control technique and A/D, D/A combination, to replace the traditional impactgalvanometer to electronic integrator, measurement is realized under the control of microcomputer simulation impact method, not only can completely eliminate the non instantaneous error classical shock method because of using ballistic galvanometer brings,and high measuring accuracy and speed fast and good repeatability.
