How strong is lightning EMP?
Lightning creates electric fields in the discharge region > 106 V/m, over an order of magnitude higher than the peak TEMP field, with power levels at approximately 1012 W, and energy dissipation between 1
How are EMPs caused?
The development of the EMP is shaped by the initial nuclear radiation from the explosion—specifically, the gamma radiation. High-energy electrons are produced in the environment of the explosion when gamma rays collide with air molecules (a process called the Compton effect).
How is electricity produced in lightning?
The warm air has water droplets. During the storm, the droplets and crystals bump together and move apart in the air. This rubbing makes static electrical charges in the clouds. When the charge at the bottom gets strong enough, the cloud lets out energy.
Can lightning create magnets?
One way lightning demonstrates magnetic properties is by creating magnets. Soil, rocks, and metal materials become magnetized when struck by lightning. Therefore, you can use magnetic links to measure lightning currents.
Does an EMP destroy electronics?
An energetic EMP can temporarily upset or permanently damage electronic equipment by generating high voltage and high current surges; semiconductor components are particularly at risk. The effects of damage can range from imperceptible to the eye, to devices literally blowing apart.
Can the Sun cause EMP?
Just as EMPs can be emitted during a solar storm, they can also be man-made, in what is known as an “EMP attack”. There are a variety of ways to generate an EMP attack, but the one that worries people the most is a nuclear weapon detonated at high altitude.
Is lightning an EMP?
Lightning can also cause an electromagnetic pulse (EMP). When lightning supercharges ions in the atmosphere, it can cause a brief, but powerful electromagnetic pulse. A power surge caused by lightning can damage electronics or cause a power outage.
Is lightning attracted to iron?
Myth: Structures with metal, or metal on the body (jewelry, cell phones,Mp3 players, watches, etc), attract lightning. Fact: Height, pointy shape, and isolation are the dominant factors controlling where a lightning bolt will strike. The presence of metal makes absolutely no difference on where lightning strikes.
