How To Protect Your Electronics From An EMP Attack

We’ve established that an EMP incident will fry all electronics. This occurs whether or not they are plugged in or turned on. This also affects automobiles, batteries, computers, medical equipment, etc. Needless to say, in such an instance, life as we know it will change dramatically. Even more distressing is the fact that the strike of an EMP is not likely to give any warning. You don’t see it. You don’t feel it. You are simply left with the sudden consequences and whatever preparedness you have on hand. So, other than your preparedness supplies, your new best friend may be a Faraday cage. In fact, with the knowledge of the protection that a Faraday cage can provide you, you may be able to enjoy nearly as comfortable a lifestyle as you did prior to any electromagnetic pulse.

The threat of a sudden EMP attack that causes a widespread catastrophe is certainly nothing new.  Consider this Cold War era quotation from a widely-read and highly-respected publication more than 30 years ago:   "The United States is frequently crossed by picture-taking Cosmos series satellites that orbit at a height of 200 to 450 kilometers above the earth.  Just one of these satellites, carrying a few pounds of enriched plutonium instead of a camera, might touch off instant coast-to-coast pandemonium:   the U.S. power grid going out, all electrical appliances without a separate power supply (televisions, radios, computers, traffic lights) shutting down, commercial telephone lines going dead, special military channels barely working or quickly going silent." -- from "Nuclear Pulse (III):  Playing a Wild Card" by William J. Broad in Science magazine, pages 1248-1251, June 12, 1981.

And oh yeah—yes, your Faraday cages DO need to be grounded. If it’s NOT grounded, then the Faraday cage merely becomes a reflector or an amplifier.

Because of the inevitability of a large solar superstorm, we have to accept the fact that the current electric power grid upon which our lives depend is only a temporary infrastructure.  This temporary infrastructure has served us very well, and we now have entrusted our very lives to it.

Faraday cages are named after Michael Faraday who invented them in 1836. They block out external electrostatic fields and electromagnetic radiation. One mistake many people make when it comes to an EMP is to compare it to a lighting bolt. The effects of an EMP and a direct lightening bolt are very similar, but they are not at all similar in terms of their visibility, and affect on the body. An EMP is more like a radio wave, not a visible bolt of light or electric current.

It’s the substrate layers of the diodes and transistors that make them susceptible to a magnetic pulse attack. Electronics are made up of diodes and transistors and substrate layers. A computer, car, television, and cell phones are made up of tons of transistors. When hit with a powerful magnetic pulse, the substrate layers are destroyed. However, early 1960’s and before electronics did not use substrate layers. They used vacuum tubes. This is why older electronics are less susceptible to damage. This is why a human or animal body will not be affected. Yes, our bodies consist of an electric volt. But understand there’s a difference between electricity and electronics.

I just want to reiterate this again. It’s important that any Faraday cage that you plan to use is grounded. It has to be grounded in order to disperse the energy.
