摘要：
We have calculated the levitation force and interaction energy between a short rnagnetic bar and a superconducting cylinder in the Meissner state using the dipole-dipole interaction model. We derived analytical expression of the levitation force acting on the short magnet as a function of the orientation angle of magnetic dipole, and the physical dimensions of the magnet-superconductor system. The effects of the thickness of the superconductor and the length of the magnet on the levitation force were studied.
