ABSTRACT:
Various levitation devices are disclosed in which an array of permanent magnets is levitated by magnetic interaction with a diamagnetic material. Levitation is achieved without using a fixed permanent magnet or other device to supplement the magnetic field of the array. The cost and design constraints resulting from undesirable spring constants produced by such permanent magnets are thereby avoided.
