"EMP attacks are the result of a nuclear explosion's fission chain reaction interacting with the earth's magnetic field and ionosphere to electromagnetically shock any system conducting electrons. Even a small, unsophisticated nuclear weapon set off in space could destroy any system dependent on electricity or the flow of electrons, transforming conducting wires into large antennas that magnify the pulse's electromagnetic shock before destroying the hard wire's ability to conduct."
