Spin and lift. A spherical magnet is attached to an upright drill with its magnetization axis in a horizontal orientation. When the drill is turned on, a second spherical magnet is drawn up and levitates just below the first magnet. The close-up image shows how the floater magnet orients its magnetization axis in a nearly perpendicular configuration with that of the rotor magnet.
