EEK! Cool! electromagnetic whistles!
I shudder to think how this effect was discovered... talk about
heisenbugs! Imagine some poor microwave receiver person trying
to find a loss of sensitivity, birdies, spurious output... and
finding out it's some goddamn FRONT PANEL LIGHT BULB!
Do you have any references to this? I have a friend who would
appreciate such horrors...
Ah, the
"Edison Effect". Some electrons (especially those
closer to the negative side) would jump away from the filament
and then, thanks to the electric field, land on the filament
but closer to the anode.
In a few bulbs, if the geometry is right, they will magically turn into
very low power magnetrons.
