In this paper, the computation of the macroscopic fields inside ferromagnetic laminations is discussed. The magnetodynamic model of non oriented steel laminations is coupled with a dynamic Preisach model. The main goal is the comparison of two numerical procedures for the magnetic field analysis which incorporate this refined hysteresis model. The two techniques are validated by the comparison of numerical experiments and measurements on an industrial material. It is shown that a very good agreement is obtained between the measured and computed material response with both techniques.
