Abstract
On the basis of the multi-domain differential quadrature, this paper formulates the equation of the magnetic field of the permanent magnet (PM), which is widely used in precision engineering. The multi-domain, including the PM domain and the air domain, is generated by dividing the whole computational domain of the PM. By applying the differential quadrature rule in each domain, the unknown magnetic vector potential can solved, and then the magnetic field distribution is obtained. Numerical results show that the magnetic field obtained by the multi-domain differential quadrature method is accurate and efficient, which is validated by the comparison with the finite difference method and the finite element method.
