Just for a small assumption...  how many watts is a battery capable of
supplying...  say a 9 volt battery.  Perhaps 4 double "A" batteries...
I'm just wondering on the ability to produce a coil from a few small
batteries and a flyback transformer.  Anyone ever tried this?  A small
handheld coil would be neat.
