May 27, 2015 at 19:19	comment	added	Nobody		I suggested toggling the field on and off. Just toggling it off wouldn't lead to the desired effect (maybe indirectly through what you describe). Toggling it on and off would reduce effective average power, but not necessarily by a lot - you could just switch it off and back on almost without time in between, wait 5s, repeat. Or you could reverse it's polarity every couple of seconds, that would also work without any reduction in power. As long as you can permanently turn it on again once you are done messing with it...
