A Faraday cage, also known as a Faraday bag, is a protective shield designed to block electromagnetic waves, such as Wi-Fi or radio signals, from getting through. This is done by using conductive materials like metal to create a barrier that prevents the signals from entering or exiting. The term “Faraday” comes from Michael Faraday, a 19th-century scientist who discovered how to shield areas from electric fields by creating a conductive enclosure. His work led to the development of this protect
