Various embodiments include a superconducting coil device comprising: a coil winding with at least one turn of a superconducting strip conductor; wherein the strip conductor has a first main face and a second main face. The coil winding includes a turning region wherein the strip conductor is bent such that, in the turning region, the strip conductor has a distinct change of direction in a longitudinal direction and simultaneously changes the orientation of both the first main face and the second main face with respect to a central axis of the coil device.
