Levitation by induction

To demonstrate levitation by induction, I have cut down a large transformer to allow an external field. It was 240 V to 110 V and rated at 2 kVA. I use the two windings in series. When run from DC it draws 15 A at 30 V or 450 W. This is enough to levitate a large NIB magnet about 17 cm away. This simple arrangement is not able to give stable levitation however but demonstrates the field strength.
