Where's the magnetism in static shocks? Where's the magnetism in a lightning bolt?
All you need is a potential.
Why are you arguing with me? Go talk to Faraday and Maxell about it. I’m sorry you don’t understand the fundamentals of physics or slept through class on the day it was discussed, but that is your problem, not mine. Go buy a book and read.
Whenever you have a flow of electricity - lightning bolts included - you have a magnetic field. You move a magnetic field by any conductor, you get electricity.
A lightning bolt generates electromagnetic waves. You can detect, locate, and even determine direction of lightning bolts via radio.
