A pulse, caused for example after a nuclear explosion, causing all electronic devices to fail due to the strong EMF. This will be the biggest problem in a nuclear war: our lives depend on electronic gadgets which will not work anymore.
Acronym for "Electromagnetic Pulse".
EMP stands for "electromagnetic pulse". Electromagnetic pulses of large amplitudes occur during lightning, close to high voltage switch gear during switching, or because of nuclear explosions (the so-called NEMP or nuclear electromagnetic pulse). Protection against EMP is one of the suject of EMC.

Electromagnetic pulse. A large burst of electromagnetic energy released by a nuclear detonation.
Electromagnetic pulse. A pulse of electromagnetic energy capable of disrupting computers. Computer networks, and many forms of telecommunication equipment.
A burst of electromagnetic radiation that creates electric and magnetic fields that may couple with electrical/electronic systems to produce damaging current and voltage surges. EMR ( Electromagnetic Radiation): Radiation made up of oscillating electric and magnetic fields and propagated with the speed of light. Includes gamma radiation, X-rays, ultraviolet, visible, and infrared radiation, and radar and radio waves.
