Abstract :
The surface integral equations whose unknowns are the surface electric current and the surface magnetic charge are widely used in static magnetic field analysis. However, the integral equations are singular at the sharp edge of the magnetic material to be analyzed and the accuracy of the computed values is poor near the edge. In order to obtain the magnetic field accurately, an edge boundary condition of the magnetic field is derived and the utilization of the edge boundary condition is discussed
