Electric Motor Made out of Buckyballs

(Video Link)

YouTube user graybum devises many simple and ingenious uses for Buckyballs, such as this amazing electric motor. It’s just Buckyballs, a wire and a battery. Redditor gloon explains how it works:

When you touch the wire to the side of the magnets, you complete an electric circuit. Current flows out of the battery, through the magnet to the wire, and through the wire to the other end of the battery. The magnetic field from the magnet is oriented through its flat faces, so it is parallel to the magnet’s axis of symmetry. Electric current flows through the magnet. If you took physics at some point, it’s possible that you’ll remember the effect that a magnetic field has on moving electric charges: they experience a force that is perpendicular to both their direction of movement and the magnetic field. Since the field is along the symmetry axis of the magnet and the charges are moving radially outward from that axis, the force (Lorentz force) is in the tangential direction, and so the magnet begins to spin.
