The Magnetic Induction of the System Consisting of a Coil and a Ferromagnetic Spherical Body.

Abstract

The magnetic induction is calculated for two configurations of a ferromagnetic spherical body surrounded by a current-carrying conductor. The first case is for an infinitesimally thin current band carrying a stationary current and surrounding a spherical shell. The second case is for a current band of finite width carrying a stationary current and surrounding a solid sphere. The ferromagnetic bodies bodies are assumed to be linear and homogeneous. The reduction of the solution for the dipole term to that of a filamentary circular current-carrying conductor is shown in the first case when the permeability of the ferromagnetic spherical shell is allowed to approach that of free space.
