摘要： PROBLEM TO BE SOLVED: To reduce the vertical displacement of superconductors with respect to time and, at the same time, to easily position the superconductors in the horizontal direction by two- or three-dimensionally arranging the superconductors, and providing a means for respectively controlling the amounts of magnetization of the superconductors. SOLUTION: A temperature control plate 1 sets the temperature of a superconductor 2 to an arbitrary prescribed value by cooling or heating the superconductor 2. The plate 1 and the superconductor 2 are surrounded by a heat-insulating material so as to prevent the flowing-in of heat from the outside. A heat exchange port 4 is provided so as to facilitate the flowing-in or flowing-out of heat to and from the plate 1. Then, the temperature of the superconductor 2 is changed, when the superconductor 2 is magnetized or the amount of magnetization of the superconductor 2 is controlled by raising the temperature of the superconductor 2 after magnetizing. By controlling the amount of magnetization in this way, the vertical displacement of the superconductor 2 with time is reduced and the superconductor 2 can be positioned easily in the horizontal direction. In addition, stable levitation can be realized by increasing the vertical and horizontal supporting force for the superconductor.
