cbseacademic.nic.in15 **Faraday Cage**: A **Faraday cage** or **Faraday** shield is an enclosure made of a conducting material. The fields within a conductor cancel out with any external fields, so the electric field within the enclosure is zero. These **Faraday** cages act as big hollow conductors you can put things in to shield them from electrical fields.
