I do not know if the wheel is aluminium or not Paul, it does not say.
But trying to con people that a steel ball is trying to climb up the inside of a wheel, with the help of a magnet, the climb keeping the wheel turning after a convenient push....is the
usual 'Perpetual Motion' con.

As it happens...try to spin an aluminium disk, with a horseshoe
magnet across its edge face. It wont spin will it?
Or try to get a small aluminium pendelum to swing across the internal face of a horseshoe magnet. It wont will it?
