For whoever understands a little more math, here is a site with the explained functioning of the device: http://cheniere.nii.net/references/found%20phys%20letters/no%201%202001/index.html.
For whoever does not know that much mathematics and still wants to know a little about Tom’s invention, here it is:
An electromagnetic generator without moving parts includes a permanent magnet and a magnetic core including first and second magnetic paths. A first input coil and a first output coil extend around portions of the first magnetic path, while a second input coil and a second output coil extend around portions of the second magnetic path. The input coils are alternatively pulsed to provide induced current pulses in the output coils. Driving electrical current through each of the input coils reduces a level of flux from the permanent magnet within the magnet path around which the input coil extends. In an alternative embodiment of an electromagnetic generator, the magnetic core includes annular spaced-apart plates, with posts and permanent magnets extending in an alternating fashion between the plates. An output coil extends around each of these posts. Input coils extending around portions of the plates are pulsed to cause the induction of current within the output coils.
The principle schematic of the device is this (click to enlarge):
“..This one works beautifully and produces COP=5.0…” says Tom Bearden
Also, here it’s the 3D model of it:
Of course, if you are interested in testing it, here’s one folk who did it: http://jnaudin.free.fr/meg/megv21.htm
