MAGNETODYNAMIC FORMULATION RESOLVING EDDY-CURRENT EFFECTS IN THE YOKE AND THE SUPERCONDUCTIVE CABLE OF THE FAIR DIPOLE MAGNETS ∗

Transient 3D simulations are carried out for two types of superconductive dipole magnets. Eddy-current effects in the yoke are treated by homogenising the laminated iron composite whereas interstrand eddy-current effects are resolved by either a cable magnetization model or a cable eddy-current model. The simulations reveal the Joule losses in the magnets.
