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

Abstract

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
