Solving Magnetic Diffusion Problems Using the PEEC Method

Abstract

In some electromagnetic problems, the paths of a current distribution in a conductor are known from the geometry or from the assumptions being used, but the magnitudes for each path are not known. The Partial Equivalent Electronic Circuit (PEEC) models the paths of the current distribution by wires carrying an unknown current. The current in each wire is found by assuming the wire forms an electrical circuit that has a resistance, a self inductance, a mutual inductance with the rest of the wires, and solving a matrix equation. Current distributions in the rails of a railgun and a copper cup are presented as examples of problems with linear and cylindrical geometries, respectively.
