The correct name is High Altitude Electromagnetic Pulse, or HEMP.  A nuclear burst at high altitude excites the living hell out of the atmosphere, and when the atoms settle back into their natural state they emit one heck of an electromagnetic pulse.  Something to be concerned about, because if Junior in North Korea figures out how to pop one at high altitude over the US it would do far more damage than popping one on the ground in a major US city.
