An electromagnetic pulse (EMP) is an intense burst of electromagnetic (EM) energy caused by an abrupt, rapid acceleration of charged particles, usually electron s. An EMP can contain energy components over a large part of the EM spectrum, from very-low-frequency ( VLF) radio to ultraviolet ( UV) wavelength s. A lightning strike produces a localized EMP that gives rise to large electrical current s in nearby wires.
