- Abstract
- A new boundary integral equation formulation for an accurate calculation of 3-D magnetostatic fields is presented. This formulation adopts a difference field concept and uses a fictitious surface magnetic charge density as the unknown. The proposed method is capable of eliminating numerical calculation errors inside ferromagnetic materials and can guarantee continuity and uniqueness of a scalar potential outside these materials. In addition, computing time and storage memory are reduced by about 75% in comparison with the total scalar potential formulation. Two examples are given to show its efficiency and accuracy.
