Abstract

On the basis of the main integrodifferential equation of magnetostatics, a problem of a sphere with an internal inclusion limited by a smooth surface is considered. An equation that must be solved only at the surface confining the inclusion is obtained. The derived equation is tested against known problems. In particular, the direct and inverse problems of a magnetic sphere placed inside a nonmagnetic sphere are considered.
