A Faraday cage is an enclosed structure made of a conductive material—such as solid metal or wire mesh—that blocks external electric fields and electromagnetic radiation from entering its interior. Invented by scientist Michael Faraday in 1836, it acts as an invisible shield, preventing wireless signals, radio waves, and electrical discharges from passing through. How It Works
