Electromagnetic pulseFrom Wikipedia, the free encyclopedia

This article is about the phenomenon in general. For nuclear EMP weapons, see Nuclearelectromagnetic pulse.

An electromagnetic pulse(EMP), also sometimes called a transientelectromagneticdisturbance,is a short burst ofelectromagnetic energy. Such a pulse's origination may be a natural occurrence orman-made and can occur as a radiated,electricor magnetic fieldor a conducted electric current,depending on the source. he term !electromagnetic pulse! is commonly abbre"iated EMP(#hich ispronounced by saying the letters separately, !$-%-&!).

$%& interference is generally disrupti"e or damaging to electronic euipment, and at higher energyle"els a po#erful $%& e"ent such as a lightning strike can damage physical obects such asbuildings and aircraft structures. he management of $%& effects is an important branchof electromagnetic compatibility($%) engineering.

he damaging effects of high-energy $%& ha"e been used to create $%& #eapons. hese aretypically di"ided into nuclear and non-nuclear de"ices. Such #eapons, both real and fictional, ha"ebecome kno#n to the public by means of popular culture.
