Abstract
A superconductive dipole magnet is simulated by a transient 3D model discretised by the Finite Integration Technique. The eddy currents in the ferromagnetic yoke are taken into account by an anisotropic conductivity tensor. The eddy currents occurring in the superconductive cable due to the finite inter-wire resistance, are resolved by a semi-analytical magnetization term added to the formulation. The simulation results indicate the importance of the eddy-current losses, especially at the yoke ends.
