The Magnetic Induction of the System Consisting of a Ferromagnetic Prolate Spheroidal Shell with Internal and External Infinitesimally Thin Prolate Spheroidal Current Bands

摘要

The magnetic induction is calculated for the configuration consisting of a ferromagnetic prolate spheroidal shell with internal and external infinitesimally thin prolate spheroidal current bands. The ferromagnetic body is assumed to be linear and homogeneous. The reduction of the solutions to that of a prolate spheroidal current band in free space is shown when the permeability of the ferromagnetic prolate spheroidal shell is allowed to approach that of free space and when either the current in the internal or external prolate spheroidal band is set equal to zero.
