hello
i dont write good english, so i hope you can understand me. i make a dream, i post it on other forum but none can help me.
my dream is to make a emp with the lightning, my idea is to make a lighting rod with a coil. when the lighting touch the lightning rod the coil emit a very short and power electromagnetic pulse (emp).
can anybody tell me if it can work and how to calculate the coil ?

What makes you think a coil would make a EMP more powerful then the strike its self? From my knowledge, EMP''s are produced with a straight conductor. Plus, theres these obvious issues: 1) safety. Trying to coax lightning to you is a death wish without proper knowledge 2) Lighting has extreme amounts of currents, that means a exploding coil. 3) the safety of a EMP pulse to nearby things. 4) practicality. Is it really practical for a hobbyist to make a lightning powered EMP?
off the top of my head, an average lightning strike is about 50KA, which isnt much more than some large hobby railguns, so i doubt the pulse would be very large. Also containing the bolt will be difficult.....I imagine it might just arc through your insulation to short the coil out.

If you want a strong EMP, you'll be much better off with something like . Of course large EMPs are very dangerous, and you'd need to do this in a very remote area.

Or not. Magnetic flux compresion devices require high explosives (NOT gunpowder), Specalized blast deflection shields to control the burn propagation, Highly precise timing of the igniter, and it all has to potted in a large block of concrete or something like that.

Yeah, good point. I guess there really arn't any non-suicidal methods for getting medium size EMPs (in between small marx gen and large nuke).

Read all posts by EastVoltResearch in this thread. He explains how an amateur would go about building an inefficient but possibly effective EMP device. It's still no easy task.
