ABSTRACT
The present paper deals with 3D magnetic field analysis of conducting current contours. The magnetic field and forces were calculated analytically and by FEM applying the Comsol Multiphysics package. Forces were calculated by the Maxwell stress tensor and by volume force density. Numerical results for real and ideal contours with the same linear dimensions are discussed. Comparison between analytical and numerical data shows satisfactory agreement.
