| 摘要 |
The invention provides a device for generating a movement, preferably a circular movement. The device comprises at least one magnet, a material which is arranged in the proximity of the magnet or in the magnet, on which material the magnet exerts an attractive force and in which the attractive force of the magnet is weakened by thermal action on at least one region of the material. The material is preferably not in superconductive state during the thermal action and preferably has paramagnetic properties prior to the thermal action and diamagnetic properties after the thermal action. |
