STATIC LEVITATION IN A HIGH-TC SUPERCONDUCTOR TILE ON MAGNET ARRANGEMENTS

Static characteristics of a levitational mechanism are studied. The levitational mechanism consists of a high-T(c) superconductor tile (type-II superconductor) and a magnet arrangement of the same size bar magnets with alternating magnetic pole pattern. The levitation pressures have hysteresis loops because of the flux pinning effect. By using the alternating pole pattern of magnets larger static levitation pressure in proportion to the arrangement can be obtained over a wide area. Moreover the levitation pressure can be optimized with respect to the width of a bar magnet of the alternating pole pattern.
