Abstract:
A superconductive coil module includes a superconductive coil a superconductive coil and a shaking coil. The superconductive coil includes a bobbin having a cylindrical shape, and a superconductive wire member of superconductive property, which surrounds an outer circumferential surface of the bobbin. The superconductive coil is configured to generate a magnetic field along a radial direction in case of a charging event. The shaking coil is disposed adjacent to the superconductive wire member, and is configured to generate an alternating magnetic field to decrease a magnitude of a screening current induced magnetic field formed in the superconductive wire member. Thus, the superconductive coil module includes the shaking coil to decrease the magnitude of a screening current induced magnetic field formed in the superconductive wire member using a voltex shaking effect to maintain a central magnetic field uniform.
