Yeah a moving/rotating magnet is the only obvious solution I see. I asked him in a second email about the price. He responded that they use some very expensive components. This indeed points towards a custom made magnetic device.How about something like this. The axis of the magnet is offset from the center of the rim, so that only half of the magnet causes, and is influenced by, eddy currents. This causes it to rotate. The rotating magnet is then simply coupled to a DC generator, which drives the LEDs.
Watch the video on the Magnic site, and you will see one view where the Magnic is clearly offset from the rim.
Makes sense but contradicts this statement "These eddy currents have their own magnetic fields (see Wikipedia) which are absorbed by the Magnic Light generator kernel"How about something like this.

There is no contradiction in Ron's idea. The interaction of the rotating permanent magnet interacts with the magnetic field generated inside the rim.Makes sense but contradicts this statement "These eddy currents have their own magnetic fields (see Wikipedia) which are absorbed by the Magnic Light generator kernel"
Unless by "absorbed" he means transferred and by "kernel" he means dynamo.
Wouldn't that set up have nearly the same same braking effect as a touch dynamo considering it is indeed a dynamo being turned?
Besides i would rather believe there is some Edward current magic going on in there

We use a technique that provides alternating magnetic fields instead of a static magnetic field. So the same with the eddy currents which are alternating and the same again in our generator.
