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

Michael Faraday was born #OnThisDay in 1791. He is most famous for his experiments in electromagnetism and his efforts to engage the public in science through the Christmas Lectures, though he came from humble beginnings as Dame Julia Higgins tells Brian Cox: | The Royal Society
