Superconducting coil device with coil and contacts

There is provided a coil device having a coil winding having at least a first and a second strip conductor. Each of the two strip conductor has a contact side with a contact layer. Furthermore, the coil means includes at least first contact between the first strip conductor and a first contact piece and a second contact between the second strip conductor and a second contact piece for connecting the coil means with an external circuit. Within the coil winding of the first strip conductor and the second strip conductor through a third contact between their contact layers are electrically connected. The first and second strip conductor differ in the orientation of the contact side to a center of the coil winding.
