Levitation Experiment of Iron Block Using Pinning Flux in HTS Bulk Material

By pinning flux in bulk high temperature superconductor (HTS), restoring force acts between iron and bulk superconductor so as to keep the position between them constant. If we could utilize this force, it would be possible to realize a low cost magnetic levitation transport system without using high cost rare earth permanent magnets. In order to confirm this idea, the authors carried out an experiment to levitate an iron block in the space between two bulk superconductors as the first step. The experimental result confirmed this levitation principle. In this paper, an experimental result of levitation experiment is presented.
