Abstract :
This work presents a new method for analyzing quasi-stationary magnetic field in hysteretic media. The vector model of hysteresis proposed here is locally Lipschitzian and monotonous. These properties assure the convergence of the fixed-point iterative procedure. The problem is set in terms of the modified magnetic vector potential. A 2-D computation example for the impulse magnetization process of a ferromagnetic domain is given
