A magnetic levitation device and method of levitating a magnet without mechanical restraining elements are disclosed. The levitation device comprises a first magnet (10) with a polygonal, preferably square, periphery and a substantially planar upper surface magnetized normal thereto and a second magnet (13) with means to rotate or spin the same. The second magnet is rotated or spun on a lifter plate (12) disposed on the upper surface of the first magnet with like-polar orientations of the magnets in confronting relation. When the lifter plate is raised above the first magnet the spinning second magnet levitates above the first magnet and the lifter plate and the lifter plate is removed from between the first and second magnets. The weight of the second magnet may be varied to change the height above the first magnet at which the second magnet levitates.
La présente invention concerne un dispositif et un procédé de lévitation d'un aimant sans éléments de retenue mécanique. Le dispositif de lévitation comprend deux aimants. Le premier aimant (10) est caractérisé par son périmètre polygonal, de préférence carré, et par une surface supérieure substantiellement plane, le champ magnétique lui étant perpendiculaire. Le second aimant (13) est en rotation ou lancé comme une toupie au-dessus d'un plateau relevable (12) placé sur la surface du premier aimant, les sens des polarités correspondantes des aimants étant en opposition de phase. Lors du relèvement du plateau relevable au-dessus du premier aimant, le second aimant tournant en toupie entre en lévitation au-dessus du premier aimant et du plateau relevable, à la suite de quoi le plateau relevable est retiré entre le premier aimant et le second aimant. La modification du poids du second aimant permet de changer la hauteur de lévitation du second aimant au-dessus du premier aimant.
