In this paper, we consider taking both microscopic excess and macroscopic classical induced losses and damping, occurring within bulk and laminated soft magnetic materials, into account. We will not detail actual eddy currents distributions but use homogenizing techniques and variational principles to derive a dedicated formulation with respect to the reduced magnetic vector potential AM, and still including specific material dynamic properties. At last, some 2-D computations are carried out and first results are discussed
