| Abstract: | The 3D finite element vector potential equations of non-linear anisotropic magnetostatic field have been derived in a pithy style by dyadic analysis. The general formulations of stiffness matrix and right column matrix are obtained, from which, we can get FEM formulations of linear and non—linear isotropic magnetostatic problems. In order to estabish FEM equations, the weighted residual method and vanational method are used in this paper, the same results have been gotten by them. The Newton—Raphson method is applied to solv non—linear problem in this paper. |
