Abstract

We present an efficient method for analyzing the influence of arbitrary time-varying magnetic fields on complex electrical circuits with the aid of the SPICE network simulator. The field-to-circuit coupling is described focussing on topological properties of the problem. After the electrical network is decomposed into tree and cotree, the influence of the magnetic field is modeled by voltage sources in the branches of the cotree. The values of these sources are determined from the geometry of the circuit using a triangulation procedure. Examples and applications are discussed
