'''Electromagnetic Pulse''' ('''EMP''') is [[electromagnetic]] [[radiation]] from an explosion (especially a [[nuclear]] explosion) or an intensely fluctuating magnetic field such as a solar storm / [[solar flare]].  The resulting electric and [[magnetic]] fields may couple with electrical/electronic systems to produce damaging [[current]] and [[voltage]] surges.  A large-yield [[nuclear weapon|nuclear warhead]] detonated at sufficient altitude has the potential to generate an EMP burst that would affect the greater part of the contiguous [[United States]].  A solar storm such as hit the [[Earth]] in 1859 would fry all [[satellite]]s in orbit and wipe out a significant portion of the world's electrical devices and [[electrical grid]]s. Depending on how strong the pulse is, unprotected electronics can be destroyed by the current and voltage surge, especially modern, more intricate and fragile components.
