The invention discloses a superconducting magnet device which comprises a low-temperature thermostat and a temperature control system, wherein an inner cavity of the low-temperature thermostat can contain refrigerants, and a superconducting coil is arranged in the inner cavity; the temperature control system comprises a temperature sensor and a refrigerating machine, the temperature sensor is arranged in the inner cavity of the low-temperature thermostat, the temperature sensor is used for controlling the refrigerating machine, and the refrigerating machine is used for providing cooling capacity for the inner cavity of the low-temperature thermostat. The refrigerant is injected into the low-temperature thermostat, the temperature control system is additionally arranged, and when the amount of the refrigerant is reduced, the temperature control system controls the refrigerating machine to work so as to convey cooling capacity to the low-temperature thermostat. Compared with the prior art that the low-temperature environment is maintained only through the refrigerant, the stability and reliability of the low-temperature thermostat can be effectively ensured through the dual functions of the refrigerant and the temperature control system, and therefore it can be ensured that the superconducting coil works stably. The invention further discloses the superconducting maglev train.
