摘要：

In order to overcome the divergence of the Newton-Raphson iteration in the nonlinear magnetic field analysis, a relaxation factor is introduced, and its optimum value is examined. It is shown that the modified Newton-Raphson method proposed in this paper shows quick and successful convergence even in the case when the conventional Newton-Raphson method fails in convergence.
