In a superconducting solenoid disposed in a cryogenic bath, the solenoid being in the form of a cylindrical annulus having a vertical axis and being composed of: two conductors (2,4) each containing superconductive material and each wound into a single layer helical coil; first and second support units (6) each supporting a respective conductor (2,4); and insulation members (8,12,14) composed of horizontal insulating layers (12) interposed between successive turns of each of the conductors (2,4), and vertical insulating layers (10) interposed between the first support unit (6) and the second support unit (6), the insulation members (8,12,14) being constructed such that variations in the current flowing through the conductors (2,4) produce varying magnetic fields which cause the insulation members (8,12,14) to experience heat-generating frictional movements, the support units (6) and the insulation members (8,12,14) are provided with a network of interconnected flow channels (22,24,26) communicating with the bath and in thermal communication with the vertical insulating layers (10) for creating a flow of cryogen from the bath and into thermal communication with the vertical insulating layers (10).
