Abstract
Purpose – The paper seeks to solve nonlinear magnetostatic field problems with the integral equation method and different indirect formulations. Design/methodology/approach – To avoid large cancellation errors in cases where the demagnetizing field is high a difference field concept is used. This requires the computation of sources of the scalar potential of the excitation field. Findings – A new formulation to compute these sources is presented. The improved computational accuracy is demonstrated with numerical examples. Originality/value – The paper develops a novel formulation for the computation of sources of scalar excitation potential.
