Electromagnetic Pulse, "EMP"
1) An electromagnetic pulse, "EMP" is a force that travels from its source outward and is absorbed in wires or circuit boards. The energy when absorbed is converted to an electric charge. If the electric charge exceeds the voltage and amperage limits of the device or a component, then the device is damaged or destroyed.
2) An electromagnetic pulse, "EMP" is a burst of electromagnetic radiation that results from a suddenly fluctuating magnetic field. Rapidly changing magnetic fields or electric fields may induce damaging current and voltage surges in electrical equipment.
