Abstract :
In this paper, a finite element method, based on a variational formulation, is used to evaluate eddy current losses inside a nonlinear, saturable ferromagnetic material, for a two dimensional field problem. Boundary conditions are imposed in an integral form combined with Neumann conditions. The dynamic field is evaluated by using an explicit integration method
