  • radial magnetic source 12 may, for example, be a single elongated toroidally shaped magnet or may be a plurality of bar-shaped magnets disposed radially about toroidal winding 14. In some applications, the energy conversion device may be used without a radial magnetic source 12.

Furthermore, if any event causes a repositioning of piston 20 relative to any of the magnet components 12, 44, or 50, the net magnetic forces upon piston 20, taking also into account the force of gravity on piston 20, will cause piston 20 to oscillate within channel 18 along longitudinal axis 16 until it is restored to a balanced stationary position.
