See all on Wikipediahttps://en.wikipedia.org › wiki › Electromagnetic_pulseAn electromagnetic pulse (EMP), also a transient electromagnetic disturbance (TED), is a brief burst of electromagnetic energy. Depending upon the source, the origin of an EMP can be natural or artificial, and can occur as an electromagnetic field, as an electric field, as a magnetic field, or as a

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.

A nuclear electromagnetic pulse (commonly abbreviated as nuclear EMP, or NEMP) is a burst of electromagnetic radiation created by a nuclear explosion. The resulting rapidly varying electric and magnetic fields may couple with electrical and electronic systems to produce damaging current and voltage surges. The specific characteristics of a particular nuclear EMP event vary according to a number of factors, the most important of which is the altitude of the detonation.

- In the 1983 made-for-television motion picture The Day After, the fictional Soviet nuclear attack on civilian targets begins with a nuclear EMP attack in order to disable as much of the United States' retaliatory capability as possible. This scenario accurately conforms to the Cold War nuclear attack scenarios as understood by military officials an...

Pulsed electromagnetic field therapy (PEMFT, or PEMF therapy), also known as low field magnetic stimulation (LFMS) uses electromagnetic fields in an attempt to heal non-union fractures and depression. By 2007 the FDA had cleared several such stimulation devices. In 2013 the U.S. Food and Drug Administration (FDA) warned a manufacturer for promoting the device for …

Electromagnetic propulsion (EMP) is the principle of accelerating an object by the utilization of a flowing electrical current and magnetic fields.The electrical current is used to either create an opposing magnetic field, or to charge a field, which can then be repelled. When a current flows through a conductor in a magnetic field, an electromagnetic force known as a Lorentz force, …

Electromagnetic Pulse. An electromagnetic pulse (EMP) is a short burst of electromagnetic energy. Such a pulse's origin may vary in size from small ones with limited effect to devastating global events destroying the entire electronic infrastructure. EMPS can be a natural occurrence, from a lightning strike, to a devastating pulse from a solar ...
