Faraday Cage:Case study

A Faraday Cage is a closed chamber consisting of a conducting material or a mesh of a conducting material.
A Faraday cage or Faraday shield is an enclosure made of a conducting matreial.
The fields within a conductor cancel out with any external fields ,so the electric field within the conductor(enclosure) is zero.
Faraday cage was first invented by Michael Faraday in 1836 and it can block external static and non-static electric fields.
These Faraday cages act as big hollow conductors ,one can put things in to shield them from electrical fields .Any electrical shocks the cage receives , pass harmlessly around the outside the cage.
When an external electric field operates on a Faraday cage,the charges within the cage rearrange themselves to direct counteract the field and thus shield the interior of the cage from the external field.
The action of a Faraday cage may depend on whether or not it is grounded.
Faraday cage can block the effects of an external field on its internal contents.
