Description

technical field [0001] The invention relates to the technical field of superconducting electromagnetic applications, in particular to a superconducting magnetic levitation track structure. Background technique [0002] High-temperature superconducting maglev has become more and more known to the public. It uses the magnetic flux pinning and quantum locking effects of high-temperature superconductors to make superconductors levitate along the permanent magnet track. However, the existing superconducting maglev track mainly fixes the permanent magnet in two ways: (1) using super glue to stick the permanent magnet on the track; (2) using magnetic force to attach the permanent magnet to the ferromagnetic track. The first method needs to paste the permanent magnets one by one while overcoming the repulsive force between the permanent magnets, which is very difficult. In the event of poor adhesion, permanent magnet arrangement error or uneven magnetic field of individual permanen...
