Effect of the Moving Speed between Magnet and Superconductor on the Levitation Force of Single-Domain YBCO Bulk
The effect of the moving speed between a permanent magnet and a superconductor on the levitation force of single-domain YBCO bulk has been studied at liquid nitrogen temperature. It is found that the levitation force is much different with different moving speed, the maximum levitation force and the stiffness of the force-distance curve are increasing first and then decreasing with the increasing of the moving speed and, there is a reasonable speed to get the maximum levitation force. It is also found that the maximum attractive force is decreasing with the increasing of the moving speed.
