Actually, there were three coils: The bipolar secondary, and an additional vertical coil on each end of the bipolar coil. The secondary coil was inside a lucite tube, and the additional coils were connected to the secondary by copper tubing. The primary coupling was fairly tight and sparks would play all over the lucite if the additional coils weren't breaking out at their breakout points.Wow! A bi-polar Magnifier! Any pictures?
Well, it wasn't really a magnifier. It just a really-long bipolar coil with the ends turned up, if you think about it. There wasn't any special driving or anything.
In fact, now that *I* think about it just this second, I *didn't* get sparks longer than the secondary! If I consider the additional length of the coil as it would have been if I would have added those vertical coils horizontally...I mean, 48" + 22" + 22" = 92"! I never got anywhere *near* that long of an arc. maybe 60".
