Abstract
A permanent magnetic male and female levitation support has a first part with a cavity and a plurality of retainment mechanisms incorporated therein, and a plurality of first permanent magnets evenly distributed around the perimeter of the cavity and held in place by the retainment mechanisms, wherein the first permanent magnets produce a first rotationally invariant magnetic field around a first axis. A second part is rigidly connected to a base and produces a second rotationally invariant magnetic field around a second axis. When the first axis is aligned with the second axis, the first magnetic field and the second magnetic field simultaneously produce a repulsive force and a restorative force to levitate the first part relative to the second part.
