A nuclear blast generates an EMP via gamma radiation interacting with air molecules to create Compton electrons. These create a brief current and an associated electromagnetic pulse. This is especially hazardous with an exo-atmospheric nuclear blast outside the atmosphere, as the region affected by Compton electrons in such a manner becomes enormous and the electrons will rotate around the Earth's natural magnetic field lines, creating a vast pulse.
EMPs and NEMPs are extremely hazardous to unshielded electronics, causing rapid fluctuations in current, especially in long wires or antennae.
2. English Muffin Pizza. The name pretty much speaks for itself; it's a pizza on an English Muffin. Very tasty with the right combination of sauce and cheese.
2. EMP's are a great dinner when you're too poor to afford a real pizza, or you're just to lazy to pick up the damn phone and call Domino's.
