Abstract	Compared with the finite element method (FEM), one dimension can be reduced in magnetic field calculation using the boundary element method (BEM). It has been proved by this paper that the convergence of integrand of integrated equation is equal to zero in magnetic field calculation and so that again one more dimension can be reduced in the investigated problems. For the 3D magnetic problem, the quadratic form function has been chosen as the correspondent magnetic potential and the singular integral has been avoided. Using these results, a new boundary element method has been developed. As an example, a 3D static magnetic field of 160 kVA rare earth permanent magnet machine with 16 poles is calculated by this new method. The calculation result shows that this new method possesses high precision.
