N2 - The electromagnetic force (EMF) between Nd-Fe-B magnets and bulk Y-Ba-Cu-O superconductors was measured by varying magnet configurations: the number of poles, magnet thickness and the addition of back iron yokes, and the shape of bulk superconductors. The EMF is strongly dependent on the magnet configuration, and therefore for the design of magnetic bearing in a superconducting flywheel system, it is important to optimize the arrangement of permanent magnets for achieving a large EMF.
