摘要

The problem of modeling of spatial planar magnetization reversal of electrical steel is considered, in which the magnetic field vectors, varying in magnitude and direction, lie in the same plane. The material operator of the hysteresis type is proposed to be found in the form of a unique function describing the nonlinear properties of ferromagnets and a linear operator modeling hysteresis. In this case, the model parameters can be determined from experimental data found in the unidirectional magnetization regimes. The results of simulation of magnetic reversal in different ways of specifying the spatial change of the field are presented. The constructed material operator can be used to calculate the magnetic field of electrical devices containing magnetic systems, which are implemented in spatial modes of magnetization reversal.
