Description/Abstract

Methods of calculating induced currents in multiply connected regions containing solid conductors are discussed. In particular, the formulation based on edge elements using the electric vector potential has been considered. The equations are explained using the language of circuit theory. It is observed that the edge values of T0 represent the loop currents in the loops surrounding the ‘holes’. It is also shown that the iterative solution may be accelerated by over-specifying the number of loop currents in the loops around the ‘holes’. The description of sources is derived for formulations expressed in terms of electric potentials T and T0. Selected results of induced current calculations are discussed and comparisons made.
