Simulation of a Normal Magnetization Curve of Electrical Steel Based on a Domain Physical Representation of Ferrimagnetic Material

详细

The normal magnetization curve of electrical steel is usually represented as an approximation curve or is set as points using a smoothing method of some sort. The equations of normal magnetization curves of electrical steel have yet to be derived due to the difficulties of physical representation of the processes occurring in ferrimagnetic materials. An attempt is made in this work to describe mathematically the magnetization of ferrimagnetic materials in the physical representation of domains, which produce a magnetic field with rotation of magnetic induction vector. Equations of normal magnetization curves of electrical steel are derived that coincide with reference data with sufficient accuracy.
