I have a question/problem with magnetic quenching. I can see how the magnetic field can divert the arc in the gap and will cause it to extinguish sooner then it would without the magnet. During the time when the energy is mostly in the secondary (notch) and the gap is filled with ions with relatively little movement, the magnetic field applies very little force (F = qvB) on the stuff you want to remove from the gap. It would seem that an air blast would work as good or better since to be effective the field needs to be very large.

Rich Hull gave us a couple of very powerful rare earth magnets. We used
them to quench a small oscillator system. I think Rich also used them in
one of his larger systems. Perhaps he could lay a few comments on. We
found them rather bulky to work with for the small benefits they provide.
