[0029] The permanent magnet rail 4 is the excitation source of the high-temperature superconductor magnetic levitation system. In order to achieve a strong magnetic field gradient, the permanent magnet rail uses a large piece of NdFeB permanent magnet 15 (size 50mm×50mm×50mm) with very high remanence and coercivity. Industrial pure iron plates 14 with high magnetic permeability are assembled. As shown in Fig. 3, during the installation process, the NdFeB permanent magnet 15 maintains the opposite magnetic polarity, and the pure iron plate 14 is located between the two magnets, which produces a strong magnetization effect. By adopting such a permanent magnet guide rail solution, a very high surface magnetic field intensity and magnetic field gradient can be achieved above the surface of the guide rail 4. The guide rail 4 uses 1 meter as a single section length. During the installation of the single section guide rail, the permanent magnets are effectively screened by testing the ma...
