There is a growing problem in solid mechanics related to electromagnetic devices of large magnetic forces such as linear motor cars, MHD systems and fusion reactors. In order to analyze the electromagnetic field, a FEM-BEM coupling method(Combination method) was proposed and has been prooved to be a promising method. However, there remains such problems that the continuity as well as compatibility on the FEM-BEM boundary are exactly satisfied or not, and that the relative advantage and disadvantage of the method are not clarified. The aim of this study is to present the formulation for applying a combination method to closed space problems using a reduced matrix and examin the compatibility of both elements by using a modified 0-1 degree boundary element. The results show the effectiveness of this method in the analysis of 2D static magnetic field.
