High Temperature Superconducting Magnetic Levitation

Fig. 7.26:Levitation forces versus height of Rail_A (a) and Rail_B (b). The height of both PMGs varied
from 15 to 100 mm.

that considering the cost of the PMG, it is not reasonable to get better levitation by
increasing the height of the PMG further.
