An electromagnetic pulse (Aka- transient electromagnetic disturbance) is a short burst of natural or artificial electromagnetic radiation. The term 'Electromagnetic pulse' is commonly abbreviated as E.M.P. and refers to a Electromagnetic phenomenon akin to static electricity, the hissing made on analogue radios by an unshielded motor and lightning. It may occur in the form of a radiated, electric or magnetic field or conducted electrical current depending on the natural or man made source. It can kill satellites, TVs, transformers, computers, etc... Exploding nukes also cause it, especially when done in the outer atmosphere.
