Abstract :
Stable levitation with a permanent magnet and a bulk high Tc superconductor (HTSC) is examined numerically by using the critical state model and the frozen field model. Differences between a permanent magnet and a trapped field magnet are discussed in terms of the levitation force property. The stable levitation region of the HTSC on a ring magnet and on a solenoid coil are calculated using numerical methods. The obtained results are discussed from the point of view of differences in magnetic field configuration
