Eddy current repulsion can provide enough force to give levitation of a coil. The coil was out of a defibrillator output circuit. Don’t know number of turns but the inductance is 10 mH (I think). It is drawing 6.5 A at 100 V AC to get the lift of about 1/2 inch off a 1/4 inch copper plate. It is tethered like a conventional lifter. The power is over 600 W so gets hot quickly.

Ultraviolet becomes visible when it makes things fluoresce. Tonic water under ultraviolet (UV) glows blue due to the Quinine content. Fluorescein glows green. “Continue reading” to see the effects of UV and the ways it is created. 10 photos and links. Continue reading
I made this as I thought I may need something to make joins for use in a vacuum that may get red hot. Epoxy and plain or silver soldering would not do. It uses a 6 V 90 A transformer and is able to spot weld a variety of mostly thin metal sheets.
