I'd always heard that it's very easy t obuild a device capabile of an EMP out of a simple circuit with a large inductor given that the inductor's voltage is given as V=DA/DT, that is, the voltage is the inverse of the change in current, which means if you have a large current going through an inductor and you cut it to zero very fast, there's some sort of electromagnetic kaboom. A reasonable home experiment might give you 1A going to 0 in 1/1000th of a second, which should give you a 1000 volt spike, but I think with a bit of finesse a device could be made to deliver a change from 10 A to near 0 to 1/1000000th of a second, or 10,000,000 v, but is that still not an issue? Sorry if I'm rattling but I'd actually curious.
