How Faraday Cages Work

How Faraday Cages Work: Faraday cages shield their contents from static electric fields. Learn how Faraday cages work and how they are used for a variety of purposes.


It has been a topic of speculation recently that North Korea could soon have an effective EMP device, which could cause devastating damage to the grid.

The way to shield against EMP devices would be a Faraday cage.  This link shows how Faraday cages work, and thus how you can protect yourself from such an attack.

It seems to me that something as simple as your car can shield from an attack.  According to the article, a car can function as a Faraday cage.  Any metallic object that fully covers an area can be a Faraday cage.

I am wondering if my concept for a building, the same thing I built for my shack, can be a cage.  If it is to be a cage, it should be completely enclosed by a conductive metal.  My shack was not.  However, it would not be much of an addition to include it.
