Abstract

A technique is presented for the computation of magnetic fields in three-dimensional multicomponent systems containing highly nonlinear materials when under the influence of current-carrying conductors. The materials must be nonhysteretic. The technique is based upon the utilization of a computer to solve: $H = H_{0} - \\int frac{\\nabla \´ \\cdot M\´}{r^{2}} r^{0} d\\tau \´ + \\int frac{n\´ \\cdot M\´}{r^{2}} r^{0} dS\´$ . The computations yield such things as the internal distribution of $M$ , the external $H$ fields, the forces between various magnetic components, and the forces between any magnetic component and the current-carrying conductors. An application to a system consisting of a superconducting solenoid and a yoke for field shaping and shielding is discussed.
