The magnetic field generated by the third magnet wall has a magnetic field gradient in the direction of motion of the vehicle. After cooling, the magnetic material enters a second generation high temperature superconducting bulk magnet in a superconducting state, and a pinning center is formed due to crystal defects such as vacancy, impurities, dislocation and the like in the magnet, so that magnetic flux is captured. As shown in fig. 3, when the second generation high temperature superconducting bulk magnet approaches the third magnet wall, the magnetic field environment of the high temperature superconducting bulk begins to change, an induced current is generated inside the high temperature superconducting bulk, and the current exists because the superconductor has a zero resistance characteristic. As can be seen from lenz's law, the induced current generated will create a resistance that will impede the vehicle from further travel in the direction of motion. Along with the carrier is closer to the buffer material magnet wall, the magnetic field intensity is stronger and stronger, the magnetic field change rate is larger and larger, and the generated induced current and the resistance generated due to the dense are also larger and larger.
