Abstract
The scalar potential of any system of axisymmetric conductors can be expanded in terms of Legendre polynomials. This paper describes a method for including the effects of a spherical iron shell into the Legendre polynomial expansion. The scalar potential is found using a surface integral approach by dividing the iron surface into elements over which the potential is constant and then using point collocation. Numerical results are obtained for a range of values of permeability by varying the number of elements and are found to agree well with the analytical results.This publication has 5 references indexed in Scilit:
