There are several designs for simple motors. This is an induction motor – moving the neodymium magnets by the aluminium can bottom will cause the can bottom to rotate because a current is induced in the aluminium. This induced current will create a magnetic field and this magnetic field is repelled by that of the magnet causing it to turn. You could also try cutting slits in the can bottom much like the swinging pendulum demonstrations.
Themes: Electricity, electromagnetism.

The stronger the magnet the better.
You need a smooth surface and the bottom of an aluminium drinks can.
