Abstract

The numerical solution of the diffusion equation in an electrical steel sheet cross section is studied with a time-dependent surface applied field. The study implements a local hysteresis magnetic law. The solutions are compared to both the classical nonlinear anhysteretic resolution and the experiment. The effect of taking into account an hysteretic magnetic law in numerical simulation is studied with different excitation frequencies
