- A metal ring placed around the core of a vertical
transformer is propelled skyward when the transformer is energized.
- The height reached can vary from zero, to a few centimeters (levitation), to several feet by changing the transformer voltage, or the type, temperature or geometry of the ring.
- Liquid nitrogen (optional) can be used to change the temperature of a ring.
(optimal core height ~23 cm)
(lay transformer down for transport)
