THE NEW STYLE EQUIVALENT SOURCE METHOD OF AXISYMMETRICAL EDDY CURRENT FIELD

Based on new style equivalent source method of axisymmetrical static field, this paper proposes a new style equivalent source method of axisymmetrical eddy current field, in which the number and positions of all the ES can be determined and the field distribution in all subregions is expressed in series form. As an example, the field distribution in axisymmetrical eddy current field has been calculated using the method. The calculated results show that this approach gives higher precision and number of unknowns to be solved is less than that of FEM or BEM.
