Application of the virtual work principle to compute magnetic forces with a volume integral method

Résumé

Magnetic forces are computed in the scope of magnetostatic problems solved by a volume integral method. This method uses the range interactions between magnetizable elements and is particularly well suited to compute the fields without meshing the air domain. This paper proposes an adaptation of the virtual work principle to the framework of the volume integral method in order to compute the magnetic forces. First, its application for electromagnetic devices in the nonlinear case allows to compute the global magnetic force. Second, its local application in the linear case provides a magnetic force density. 3D numerical examples are given, and the results are compared with the analytical solution and the finite element method.
