Analysis of magnetostatic field for some class of inhomogeneous problems by BEM Available to Purchase

Presents an application of the boundary element method to the analysis of magnetic fields in materials for which permeability depends non‐linearly on spatial co‐ordinates. A new approach is proposed, which relates the Green’s function for non‐linearly dependent permeability to Green’s function of the Laplace equation in free space by adequate variable transformation. This can be done for very broad class magnetic permeabilities. These permeable functions, which cannot be directly used in such transformations, can be approximated by series of admissible functions.
