Electromagnetic Pulse (Electromagnetic Pulse) in the nuclear explosion, lightning, sunspots, conduit effects and electrical sparks and other conditions can be generated. One of the nuclear explosion produced by the Y-ray, with the speed of light from the explosion point to the surrounding radiation, and the air oxygen, nitrogen atoms collision, and produce negatively charged electrons, resulting in the formation of extremely strong electromagnetic field, commonly known as electromagnetic pulse. It is the 40s in the high-altitude nuclear explosion test was found. It can be in a very short period of time, in the form of electromagnetic waves, will be a powerful energy from the point of explosion to the distance, in the process of traveling, will be electronic, information, cables and other facilities to produce heat destruction effect, so that the task can not be effectively carried out. As the electromagnetic pulse on the human body almost no direct harm, and specializing in electronic systems for the destruction of the target, in order to paralyze the enemy command, control, communications, computers, intelligence and surveillance systems for the purpose of measuring the future of high-tech wars, a variety of scientific and technological weapons, are upgrading the ability to engage in electromagnetic impulse to take the first "system of electromagnetic power," and then dominate the battlefield! The main reason for this is that it is not possible to make a difference in the way the world works.
The so-called electromagnetic pulse is an instantaneous change of electric and magnetic fields. Figuratively speaking, the electromagnetic pulse is like the electromagnetic signal produced by lightning during a thunderstorm. The strong electromagnetic pulse generated during a nuclear explosion is called a nuclear electromagnetic pulse. The physical cause of nuclear EMP is the nuclear explosion release of γ-rays, it is the speed of light and air molecules touch, high energy γ-rays will be separated from the air molecules of electrons, and make the electrons quickly diffuse to the outside.
