Death by Powerpoint
All commentary aside, a plunger type launch control seems quite appropriate for a fair number of launches (a number of my own included) I have observed.
Something like this?

On the test bench because it didn't put out any voltage. The problem turned out to be that the magnet had lost its "mojo". How does that happen? How can I re-magnetize it? This was for launching sounding rockets.

No. Why would you want to.
that looks so cool, basically exactly what I was imagening. I can't help with the issue though sorry. I've heard that magnets can become non magnetic but I don't know how or if it's fixable. Did it use to work properly?
Yea, pretty close, though I had pictured mine to look just like the the original TNT detonators. Weathered barn board box, with a big rusty T-handled plunger, brass screw terminals, cloth wrapped wires...you know? Old school
For some odd reason, can't find -those- on Ebay?! Hmm...?
What you've done is made a capacitive discharge ignition system. If you don't want to crank it up, you can take the photoflash circuit from a disposable camera instead of the hand crank generator, but beware, the voltage/current pulse can be dangerous and potentially fatal.I used a war surplus GN-38 generator from a field telephone and made a good launch controller that never needs batteries. You have to crank it for 45 seconds or so to build up the charge. Attached is an article I wrote but never got published.
