    Correct, no relative motion between the parts. It is being driven by another magnet some distance away. It is at 90 degrees to the driving magnet. I let it spin about 10 minutes before I stopped it. The assembly is held together with grey duct tape and it spins at about 3000 RPM's and rolls much...
