I saw this video once of a wheel, surrounded by magnets, spinning like mad (accelerating/decelarating at will be moving the magnets closer/further from the wheel)

Why doesn't that work?

perpetual motion machine = an endless motion right? (which isn't really possible as some of the energy put in to the machine will always get lost in some form of friction or whatever).. but what was the story on the magnet wheel?

maybe it does succumb to friction, just very slowly.
