Abstract
It is pointed out that nonlinear magnetostatic field problems must be solved by an iterative approach, either by direct iteration or by the Newton-Raphson method or by a combination of both. Some improvements are described here to decrease the number of iterations that are necessary to arrive at reliable results. CPU-time requirements with and without these improvements are compared. The improved software package is applied to an inverse problem, in which the form of the pole of a C-shaped nonlinear magnet is to be optimized
