Well, after some thought. I came up with this.
#1 suggestion, Place a largeish magnet to push the magnetic field coming off the solinoid out of the way. if the magnet you place behind the HES is strong enough, the field from the solinoid won't be enough to get teh HES out of hysterisis, and therefore get that fun f/a effect.
#2 Magnetic field shielding... There are materials that are "dimagnetic" Say... a block of graphite could hide the magnetic field of the solinoid plunger. Or it could be used around the HES so the HES can only see the magnetic field of the trigger magnet.
IIRC bismoth is also dimagnetic. But to a much smaller degree.
food for thought...
