The invention provides a high-temperature superconducting magnet for maglev electromagnetic propulsion and a maglev train. The high-temperature superconducting magnet comprises an outer Dewar, a cold shield, a superconducting switch, an inter-coil joint and two superconducting coil units which are symmetrically arranged, the inner part of the outer Dewar is in a vacuum state; the cold shield is arranged in the outer Dewar, and the first cold head penetrates through the outer Dewar and is connected with the cold shield to cool the cold shield; the two superconducting coil units are arranged in the cold shield, and each superconducting coil unit comprises a coil box, a superconducting coil, an iron core, a current lead, a supporting part and a cold conduction fin; the coil box is provided with an annular groove and a through hole; the superconducting coil is arranged in the annular groove; the iron core is arranged in the through hole; the cold conduction fin is arranged on the coil box, and the secondary cold head is connected with the cold conduction fin; the superconducting switch is arranged in the cold shield and is connected with the superconducting coil; and the coil-to-coil joint is arranged in the cold shield. The high-temperature superconducting magnet can solve the technical problem that a high-temperature superconducting magnet in the prior art is low in propulsive efficiency and flow capacity.
