I didn't have any copper tubing for my tesla coil, so I used steel wire , about 12 gauge. Will that work? It made some small arcs from from a tabletop coil driver (no the driver did not burn out) when I quickly tested it. The arcs were only around an inch, but would it work if I had a power supply that would actually be used to power something this size, and not a small coil? For example, flyback or NST? I wasn't sure if steel would work.
