P2.27 Magnetic levitation trains provide a high-speed, very low friction alternative to steel wheels on steel rails. The
very low friction alternative to steel wheels on steel
rails. The train floats on an air gap as shown in Figure
P2.27 |25]. The levitation force F, is controlled by the
coil current i in the levitation coils and may be ap-
proximated by
relationship between the air gap z and the controlling
current near the equilibrium condition.
