Electromagnetic Pulse

An Electromagnetic Pulse, or EMP, is a burst of electromagnetic radiation (light, magnetism, electricity), and is caused by a huge release of energy. A "common" cause for an electromagnetic pulse is a nuclear explosion. A scientist named Enrique Fermi predicted that electromagnetic pulses would result from a nuclear weapon being launched. An EMP can damage electronic recording equipment and shut off digital clocks, regardless of their electronic shielding.
