Abstract
A coil device with at least one electrical coil winding with superconducting conductor material and a vacuum container is described in which the vacuum container surrounds the coil winding. The coil winding is part of a self-contained circuit for the formation of a continuous current. The closed circuit has a switchable conductor section, the conductor of which can be switched between a superconducting state and a normally conducting state by a magnetic device. The magnetic device has an internal part arranged inside the vacuum container and an external part arranged outside the vacuum container.
