The device was a coil wound around an iron rod that was supplied with an alternating current. An aluminum puck was placed on the iron rod, and wnen AC current was applied, the puck would fly off of the rod. I would like to build a similar project to demonstrate induction in non magnetic substances. Dad can't remember exactly how he built the project. It was a shop project in Riverside CA. My dad says that eddy currents introduced into the aluminium puck caused it to have a magnetic field opposite to the field in the coil and iron rod, causing it to be repelled and fly off. I would like to build one to experiment with. I would like to usa a 6 volt AC source for the coil. Can you help? Please reply to my dad's Email, email@example.com Thank you, John True
