Background. Quality improvment of the products, containing electrical steels or precision soft magnetic alloys in their composition, is based on the express-analysis of their magnetic properties in the production process. It can be carried out quickly and with sufficient accuracy by using computer measuring complexes (CMC). The purpose of this work is to develop such complex to study parameters of hysteresis loops and a basic magnetization curve of soft magnetic materials and magnetic circuit parameters in constant magnetic fields on the basis of the induction-pulse method with a switching mode variation of the magnetizing field. The block diagram of the CMC was developed, requirements for magnetization block components were explained, the approach to the definition of a number of magnetization block ranges and integrator channels allowing to achieve the desired accuracy and precision of measurement of static magnetic characteristics was suggested. The authors proposed methods for minimization and registration of an integrator drift.
