Faraday
A Faraday cage is an enclosure made of conductive material that blocks external electromagnetic fields. It protects whatever is inside from a damaging pulse or surge. Named after physicist Michael Faraday, smaller versions are sold as Faraday bags or Faraday pouches.
Why Preppers Use Faraday Protection
You meet the term when you plan for an EMP or a severe solar flare. Either event could disable unshielded electronics across a wide area. Spares stored inside a Faraday cage, such as a backup radio, a spare phone, and power banks, keep communication and light working through a grid-down aftermath.
