# Description

TEAM (Testing Electromagnetic Analysis Methods) represents an open international working group aiming to compare electromagnetic analysis computer codes. TEAM Workshops are meetings of this group. A series of TEAM Workshops was started in 1986 and has been organized in two-year rounds, each comprising a series of ”Regional” workshops and a ”Final” Workshop, as a satellite event of the COMPUMAG Conference. The TEAM problems consist in a list of test-problems, with precisely defined dimensions, constitutive laws of materials, excitations, etc., and each backed by a real laboratory device, on which measurements can be made.

The TEAM 20 problem is a non linear magnetostatic 3D model for verification of magnetostatic force calculation. The center pole and yoke are made of steel and the coil is a source circuit with imposed Ampere-turns. This model allows to investigate the surface magnetic force calculation obtained by the monolithic solver in magnetostatic cases under different current excitations.
