ABSTRACT:
A magnetic levitation system for supporting an object against gravity by a supporting force includes a permanent-magnet dipole aligned in a vertical position and coupled to the object, a supporting-field generator and a stabilization system. The supporting-field generator generates a supporting force on the permanent-magnet dipole via a supporting field. The supporting field is a two-dimensional or three-dimensional magnetic quadrupole field so that the supporting force is independent of a position of the dipole. The stabilization system constrains the dipole against movements in at least one horizontal direction, and includes a diamagnetic element coupled to the dipole and arranged below the dipole, and a stabilizing-field generator generating a second two-dimensional or three-dimensional stabilizing field to restore said diamagnetic element to a position where the field strength of the stabilizing field has a local minimum.
