Physics behind Crealev's devices.

  1. Oct 23, 2011 #1
    I am interested in hearing your comments about the physics behind Crealev's levitating devices (http://www.crealev.com/). It is known you can beat Earnshaw's theorem using spinning magnets:
    http://en.wikipedia.org/wiki/Spin_stabilized_magnetic_levitation

    but in Crealev's devices it seems there are no moving parts (and of course no superconductors).

    Could it be diagmagnetism created by Eddy currents?

    it does not show much about the base... from what I understand you can levitate a permanent magnet by rotating the fields around it. So my guess is that there may be a permanent magnet in the levitated object, while the base provides a dynamic field. you don't need moving parts in the base either, just a configuration of coils and some electricity.
