Hi Jerry,

could be wrong on this, but, it sounds like what is referred to as steel
wire being used in a Tesla coil is in fact the windings of the Tesla coil
itself are steel. Steel windings instead of Copper? Made a lot of Tesla
coils in my time but never tried this. What effect would steel windings
have???

Bill.
