Abstract

Material derivatives for electromagnetic fields are presented. They are applied to determine the Maxwell stress tensor associated with different models of ferromagnetic materials. The accent is placed on the theoretical implications of the simplifying assumptions done in the different material models, with a thermodynamically consistent finite-element implementation of electromagnetic forces in scope.
