An expression of the magnetic co-energy adapted to magnetostatic volume integral formulations - application to the magnetic force computation

Abstract : This paper provides a new expression of the magnetic co-energy for ferromagnetic materials. This expression is very well suited to integral methods but can as well be used as a post function for the Finite Elements Method (FEM). First the context of this work and the expression of the co-energy will be introduced. Second, two examples will be treated with the proposed method and the performances will be compared with the FEM.
