Axial-field eddy-current coupling : a 3D test problem for numerical experiments

International audienceThis paper deals with a device which is particularly relevant to test 3D quasi-static magnetic numerical computations: axial eddy-current coupling. The authors have performed several numerical FEM computations for this particular device. The eddy currents problem is solved thanks to two classical formulations based on magnetic vector and scalar potentials. Results are compared with experimental measurements made on a magnetic transmission already designed and built
