Abstract
A magnet coil (30) comprises at least one first winding made of wire (34) which is superconductive at operating temperature and at least one second winding made of normally conductive wire (36). In addition, means are provided for supplying a current into the second winding, which is completely dead during superconductive operation of the magnet coil (30), when at least certain sections of the superconductive wire (34) assume the normally conductive state. In order to accelerate the spatial propagation of this transition in the magnet coil (30) and at the same time to provide the possibility to use low-cost wires having a relatively small proportion, related to the cross-sectional area, of normally conductive material, the first and the second winding are connected in parallel electrically.
