ABSTRACT:
A magnetically levitated object provided with a magnetic suspension system consisting of support magnets which magnetically cooperate. The levitated object is maintained in a stable condition by means of a stabilizing device which substantially comprises two main magnetic elements one of which is connected to the levitated object and comprises at least one stabilizing permanent magnet. The second main element includes a system which generates a constant amplitude magnetic alternating field in which the stabilizing magnet is disposed. If the levitated object is to be stationary, an electric coil surrounds the stabilizing magnet. In the case of a moving object, such as a levitated train, each carriage -- suspended or standing -- is provided with a row of stabilizing magnets which are arranged parallel to the magnet rail and are alternately magnetized in opposite directions. A linear damping system may be used to restrict any oscillations.
