If only ppl would learn to use these with tesla coils! It makes a BIG difference when the coild is pulsed DC and NOT AC

@DarkShroom instead of a nice smooth wave signal you'd have a periodic spike. Cap discharge spark gaps are used in tesla coils often to perturb the proverbial string that is the inductor / capacitor resonant circuit. By using this magnetic quench approach the inpulse duration is shorter and thus a higher instantaneous power is produced.

what did you use to make this send me drawing

@cheaphardwarez sorry i meant equvilent of ac
-
@cheaphardwarez forgive my ignorance but isn't pulse dc the electircal equivilent of as as it just to full potential then drops back to 0? is it better for sparks perhaps because you're always pushing the electrons one way?

verry nice!

the capacitor lookes like a c1 class 200v 1uf film capacitor though

So is it discharging more frequently due to Lorentz force or why it sounds that the spark frequency gets higher with the strong magnet.

@SpecklePattern It only takes me 1 year to reply... sometimes... I think the sound is higher/louder because the discharge is more abrupt. The energy from the capacitor discharge is not allowed to be a "soft" discharge, it has to happen more suddenly because the lorentz force is pushing on the arc as current flows. This probably causes the cap to charge a little higher before it can discharge again, and so, more energy louder sound.

Nice work johnb003,
a neo magnet can do what a 555 and transistor does for switching.
Have a look at my video response
Thanks for sharing.

You're right you could do it, cool video!, but I don't think it would be better than a 555. I think it's the same as using a relay, and then you still have a low current limit and need to use a transistor or power mosfet, and the relay has mechanical contact sparking which, if nothing else, will wear it down faster.
