【Abstract】 In the area of the study of electromagnetic fields, numerical methods have found increasingly wide use. This paper describes systematically the basic contents of the finite element method used for numerical analysis of steady electromagnetic fields. The paper gives the results of the numerical analysis of steady electromagnetic fields in linear and non-linear mediums using the united matrix form. By giving examples embodying the use of automatic mesh generation methods,and in particular the method of successive triangular elements, the paper further explains the theoretical basis of the finite element method and illustrated the practical value of the method for wide application and popularizations.更多还原
