A Novel MSFEM Approach Based on the A-Formulation for Eddy Currents in Iron Sheets

The multiscale finite element method has been shown to be an efficient tool in the simulation of eddy currents in laminated cores. This paper presents a novel multiscale formulation which corrects some shortcomings of the current method, giving a more physically meaningful solution that is more accurate than the current formulation while also requiring less degrees of freedom.
