The BPS of a static gap is whatever it "needs to be", determined by the
gap width, cap size, and power supply. Sorry to be so vague, but there
is no specific target number, and it's not related to mains-resonance.
Lower figures generally result from higher C values and/or higher
voltages, resulting in greater bang sizes and better performance. From
a post I submitted last year:
I just measured the BPS of my mini coil, using a partially-deshunted
4/20 NST. Using a digital storage scope, I scoped the field coming off
the secondary over a 400 msec interval with a scope probe hanging about
8 feet from the coil. I tried 3 different cap sizes:
Cap BPS
.012uF 297 BPS
.02uF 207 BPS
.025uF 157 BPS
