Description

technical field [0001] The invention relates to the field of superconducting magnetic levitation, in particular to a high-temperature superconducting coil magnetic levitation test device. Background technique [0002] The phenomenon that the resistivity of a superconductor suddenly disappears when the temperature of the superconductor drops below a specific critical temperature is called the zero resistance effect of the superconductor. Due to the zero-resistance effect, superconducting coils wound with superconducting wires can withstand large currents, thereby generating very high magnetic fields. The magnetic field generated by the continuous current flowing in the superconducting coil interacts with the external magnetic field to produce superconducting magnetic levitation. [0003] High-temperature superconducting maglev trains are one of the important applications of high-temperature superconducting coils in the field of maglev technology. When designing and developin...
