Some things with a magnet over a copper plate I have not seen before

[Magluvin]

Here is a vid that has a lot of what we have seen before. But at 3:30 into it is some very interesting stuff i have not seen. Seems to emulate a magnet floating over a superconductor. Check it out.  Nice vid altogether with slow motion takes also.

Hmm could you make a room heater with just by running magnets over a copper plate? Would take a lot less electricity than heating metal to red hot. Just make a wheel with N poles pointing outwards and turn that wheel fast.

Since there is no cogging you could turn the wheel with power from an antenna

Sorry Belfior,

But cogging is not the only reason there is a load on a generator.  As current flows it creates drag also which is known as Lenz law.  Turning the magnets past a copper plate will heat the plate.  The reason it heats the plate is because of the eddy currents induced in the plate by the passing magnet.  The eddy currents in turn create drag on the moving magnets.  So it does take power to move the magnets past the copper plate even though there is no cogging.  And I have seen on another forum a member that did build a heater just like that.  It was pretty efficient but it did take a strong motor to overcome the drag of the magnets moving over the copper plate.
