To the calculation of three-dimensional magnetic fields by numerical methods.

Abstract

We consider the formulation of the problem of calculating a three-dimensional stationary magnetic field taking into account the nonlinear properties of ferromagnetic materials. The results of solving a three-dimensional field problem in an electromagnetic device are considered. A comparative analysis of various methods for solving systems of linear algebraic equations when solving a nonlinear problem of calculating a magnetic field by the Newton method is carried out.
