I've been trying to find out some info on EMP blasts and how to protect one's stuff from them and have nothing but contradictory answers. Does anyone on here have any good info? Some of my questions are:
-what exactly does EMP affect? Just things that are "on"? Anything that uses or creates elec power? Will plugged in things just cease to work, or explode, catch fire, etc? What about simple battery stuff like a flashlight? The batteries themselves? Pacemakers? What needs to be replaced on a car to get it up again? Can those parts be stored in some way so as to always have good replacements?
Any light that could be shed would be great. Thank you.

As far as I know it has to do with the circuitry. Simple electronics flashlights ok, led flashlight nogo. Late 60a-early 70s autos ok, problem with computers in late mod. cars among other sensors and crap. Put any electronics you don't want fried in a metal ammo can or any sealed metal container. Only problem is I don't know how to tell when It's over and safe to use items. Is say a pacemaker would be knocked out. I'll look into it a little more and let you know more tomorrow.
