Abstract :
Effect of the dynamic magnetic hysteresis on the induced currents is investigated. The method used combines a finite element simulation and a dynamic hysteresis modeling. 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.
