I wish your opinions (analyses) on this simple demonstration posted on
another list.
A lamp and inductor in parallel are powered by a DC supply (battery)
thru a switch. Opening the switch causes the lamp to flash. (nothing

field, e.g. large magnetron magnet, the flash is brighter and burns out
some bulbs, e.g. 25 W (110 V. I presume)
