Three thousand volts per millimeter....Thats the breakdown voltage in air. And that's just standard temperature and pressure air, mind you...Not combusting air/fuel mixture at 1200 degrees Fahrenheit...
Who makes it all possible, 2900 times per minute ?
This little guy.
Take the cap off the top of your Magnetos and you can explore his unreal world, trapped in a little plasma hell he never made.
And what does he ask in return ? That he can be rotated freely inside that bakelite sleeve he sits in. So maybe the special Slovenian Udder grease coating got a little hot, solidified and now he's stuck.
It's just a matter of time until breakdown.
And when that happens, you'll be bucking like a rodeo rider for a few seconds, you'll switch mags, return safely to the ground and switch him out with that spare you had on the shelf.
