Abstract
In this article, the diffusion of electromagnetic fields into a ferromagnetic lamination is numerically studied by means of an error-based numerical method. This technique has been developed so far only for the case of nonhysteretic constitutive relations. The generalization to the hysteretic case requires a modification of the technique in order to take into account the evolution of the “magnetization state” of the media. Numerical computations obtained by using this approach are reported and discussedFile in questo prodotto:
