In this paper, we present a numerical procedure capable of analyzing dynamic hysteresis in axial-symmetric problems. The ferromagnetic hysteresis is described by Jiles-Atherton model. This model is integrated in finite element method (FEM) in order to resolve magneto-dynamic problems. The interface between the Jiles-Atherton model and the finite element magnetic vector potential formulation is introduced through the fixed-point iterative technique. The simulation results obtained are intended to give an explanation and understanding of nonlinear behavior of ferromagnetic materials and their effect on the magnitudes of the electromagnetic system.
