electromagnetic pulse

electromagnetic pulse (plural electromagnetic pulses)

1. A short-duration burst of high-intensity electromagnetic radiation generated by a physical event, in particular by a large thermonuclear explosion in the atmosphere. The pulse causes a damaging surge of voltage within electrical and electronic systems.
2. Compton-recoil electrons and photoelectrons from photons scattered in the materials of a nuclear event causing electric and magnetic fields to couple with electrical and electronic systems to produce damaging current surges.[1][2][3]
