A container made of a conductor, such as wire mesh or metal plates, shielding what it encloses from external electric fields. Since the conductor is an equipotential, there are no potential differences inside the container. The metal hull of an aircraft acts as a faraday cage, protecting its occupants from lightning. Faraday cages are used to protect electronic equipment from such electrical interference as electromagnetic interference.

A shielded enclosure used to block electric fields from reaching its content. Constructed of metal, the cage conducts current on its exterior but prevents it from reaching inside. The Faraday cage was invented by physicist Michael Faraday in 1836.Home-made cages are made by wrapping a cardboard box with aluminum foil or using metal garbage cans or anti-static bags. Items placed inside can also be wrapped with layers of aluminum foil. See EMP and Farad.
