An iterative procedure for calculation of 3D magnetostatic field in no
nhomogeneous, nonlinear, and anisotropic regions of electromagnetic ac
tuators has been presented. In the proposed method, the 3D task has be
en substituted with a sequence of 2D problems, so it was possible to a
dapt the algorithm worked out to PC 486 computers. The decomposition o
f the problem consists in: (a) separation of magnetic vector potential
components, (b) partition of the considered region with a number of s
urfaces with 2D discretization.
