Hi Horace, That is an interesting idea you have suggested. I was thinking along the same lines until I realized that the energy was never returned by reversing the movement. Does compressing the B into a higher average pressure result in storage of the energy instead of converting it into heat? If it is stored as I would assume that the energy would be returned if the movement reverses. Do you see my point? Is it possible that the movements toward and back make a permanent(pinning energy?) modification to the internal structure of the disk? Maybe this is related to the effect that occurs when an alternating field of RF is applied. An interesting thought is that the RF field simulates the physical up and down movement at a much higher rate.

Can you give me an answer to my question? It appears that energy can be put into the floating disk-magnet combination by pushing or pulling against the disk. Where does the energy show up in the system? Does the disk heat up a small amount as I push or pull on the disk or does the magnet get the energy? This question may be related to the amount of force required to displace the disk. There may be important information revealed as a result of the energy transfer. I eagerly await your answer. Dave Hi Dave, Here is guess for you. The magnetic pressure P = B^2/(2*mu0) is reduced in the volume immediately below and above the puck, except in the thin volumes near the puck of flux transiting the thin vortices in which lines of flux are pinned. The magnetic pressure immediately adjacent to the sides of the puck, and adjacent to the pinning locations is increased. Any movement of the puck relative to a given magnet, provided the movement does not involve a canceling symmetry, such as rotation above a single magnet, or movement on a single magnet track, changes the local B and/or volume in which the B resides, and thus magnetic pressure, and thus energy of the system. Pushing the magnet into place merely involves compressing the B into a higher average pressure, and thus consumes energy. The energy in the B resides in the polarized vacuum.
