A burst of electromagnetic energy. In a military context—and the subject of this article—an electromagnetic pulse (EMP) is a transient electromagnetic signal produced by a nuclear explosion in or above Earth's atmosphere (Fig. 1). Though not considered directly dangerous to people, EMP is a potential threat to many electronic systems. See also: Atomic bomb; Electromagnetism; Electronics; Hydrogen bomb; Nuclear explosion
