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.
