ABSTRACT:
In one embodiment, a superconducting coil includes a tertiary parallel superconductor unit (60) composed of superposed in parallel a plurality of layers of secondary parallel superconductor units (50). The layers of secondary parallel superconductor units include a plurality of superconductor elements (40) arranged in parallel along the axial direction of the coil, forming a superconducting conductor unit. The tertiary parallel superconductor unit is wound on a bobbin (55). In another embodiment, the superconducting coil includes one or more layers of the secondary parallel superconductor unit wound on the bobbin. In both embodiments, the secondary parallel superconductor unit can include at least one non-superconducting conductor element (70). The layer of the secondary parallel superconductor unit forming an outer side of the tertiary parallel superconductor unit can include at least one non-superconducting conductor element. A layer of non-superconducting conducting or high-strength insulating supporting member (71) of electromagnetic force can be formed on the outer side of the tertiary parallel superconductor unit.
