Abstract

There is a great multitude of different approaches to compute magnetic forces, each of them giving different results. Therefore, in this paper three popular force computation methods are investigated for nonlinear magnetostatic problems with the integral equation method. Computed results are compared with measurements from two setups. First, the recently presented TEAM Workshop Problem No. 33.a is used since it allows for verification of force densities. Second, the computed total magnetic force acting on a body is verified with the TEAM Workshop Problem No. 20.
