[LEVITATOR GIF: 2 rows of 6 tilted coils, with bar magnet floating above them] Here a 3 inch alnico rod magnet is levitated by the cradle. Below the magnet are two rows of tilted coils. On the core face of each coil is the Hall device which provides the feedback-generated repulsion profile between the magnet and the coil. This particular version was only marginally stable, and the bar magnet would remain levitated for several seconds before oscillations built up and ejected it from the device.
