'''Electromagnetic pulse''', or '''EMP''' is the electromagnetic radiation from an explosion (especially a nuclear explosion) or an intensely fluctuating magnetic field caused by Compton-recoil electrons and photoelectrons from photons scattered in the materials of the electronic or explosive device or in a surrounding medium. While organic tissue is unaffected, the resulting electric and magnetic fields may couple with electrical/electronic systems to produce damaging current and voltage surges. The effects are usually not noticeable beyond the blast radius unless the device is nuclear or specifically designed to produce an electromagnetic shockwave. An alternate definition is: a broadband, high-intensity, short-duration burst of electromagnetic energy. | '''Electromagnetic pulse''', or '''EMP''' is the electromagnetic radiation from an explosion (especially a [[nuclear weapon|nuclear explosion]]) or an intensely fluctuating magnetic field caused by Compton-recoil electrons and photoelectrons from photons scattered in the materials of the electronic or explosive device or in a surrounding medium.

The worst of an electromagnetic pulse generally only lasts for a second, but any unprotected electrical equipment will be affected by the pulse. | The worst of an electromagnetic pulse generally only lasts for a second, but any unprotected electrical equipment will be affected by the pulse. | ||

*In the aftermath of [[Operation: UPPER CUT]], both [[SPARTAN-B312]] and the satellite [[Navigation Beacon RA-15]] witnessed a purple-tinted EMP cloud emanate from the wreckage of the [[Covenant supercarrier]] ''[[Long Night of Solace]]'' after the improvised slipspace bomb was activated. The cloud disabled all electronics within its vicinity, including the NAV Beacon. | *In the aftermath of [[Operation: UPPER CUT]], both [[SPARTAN-B312]] and the satellite [[Navigation Beacon RA-15]] witnessed a purple-tinted EMP cloud emanate from the wreckage of the [[Covenant supercarrier]] ''[[Long Night of Solace]]'' after the improvised slipspace bomb was activated.
