A Magnetic Vector Potential Formation to Deal with Dynamic Hysteresis and Induced Losses with Two-Dimensional Models

We consider taking both microscopic excess and macroscopic classical induced losses and damping, occurring within bulk and laminated soft magnetic materials, into account. We won´t detail actual eddy currents distributions but use homogenizing techniques and variational principles to derive a dedicated formulation with respect to the magnetic vector potential. At last some two-dimensional results are discussed
