This invention discloses an ultra-high current density superconducting magnet and its wireless excitation device. The superconducting magnet includes superconducting magnet coil units and multiple superconducting strips connected in parallel. Each superconducting magnet coil unit includes a magnet coil frame and magnet coils wound on the frame. The superconducting magnet coil units are stacked, with one end connected to a busbar of one superconducting strip and the other end connected to a busbar of another superconducting strip. The two busbars are connected by superconducting flying wires. This invention uses a parallel connection to automatically distribute current among the coils. When the operating current of one coil exceeds its critical current, the current automatically flows to other coils, causing the current in coils whose operating current has not reached the critical current to continue to increase. Ultimately, all coils can operate close to their respective critical currents, increasing the operating current of each coil and significantly improving the engineering current density of the magnet.
