1. I would think the quenching time (if it is affected by the magnetic
field) would vary INVERSELY as the magnetic field, since the force is
proportional to the field times the current flowing.  Higher flux would
accelerate the ions "sidewise" more and result in shorter time.

2. There is no force until a current flows so I can't say any way
magnetic flux could prevent the gap from firing.
