摘　　要：讨论了非线性磁场的计算问题 ,指出如何确定磁场磁阻率是影响计算收敛的重要因素。提出在磁场饱和情况下保证采用线性迭代法计算也收敛的方法。In this paper, the calculation of nonlinear magnetic field problems was discussed and it is an important influence factor on convergence that how to determine the magnetic reluctivity was pointed out. An improved method, which ensures the calculation is convergence by linear iterative method for saturated magnetic field, and an optimum convergence method of solution for nonlinear magnetic field problem if there are inflection points on the magnetic curve were provided.
