本文用库仑近似给出了径向极化永磁体标量位场和标量磁场的新的半解析表达式。它采用虚拟磁荷来模拟磁场强度。利用这个快速模型，我们可以计算永磁体内部各点的退磁场和外部磁场。
New compact semianalytical expressions of the scalar potential and magnetic fields produced by a radially polarized permanent magnet are described in this paper by using Coulombian approach. It uses fictitious magnetic charge to model the magnetic field intensity. With this fast model, we can compute the demagnetization field in each point inside the permanent magnet and the magnetic fields outside it.
