A Faraday Cage is an enclosure made of conductive materials that blocks external electric fields. It works by redistributing electric charges on its surface, which cancels out the field's effect inside the cage. This principle is named after the scientist Michael Faraday, who discovered this phenomenon in the 19th century. Faraday Cages are used in various applications, such as protecting sensitive electronic equipment from electromagnetic interference. They can be found in laboratories, vehicles, and even in some buildings to shield against lightning strikes and other electrical hazards.
