Faraday Cage

The term “Faraday Cage” refers to what physicist Michael Faraday, invented in 1836. Also known as a “Faraday shield,” Faraday cages do not have to take the form of an actual cage, but rather they can be any sort of enclosure surrounded by or lined by a mesh of conducting material that blocks electrical fields and radio frequencies.   Its use in paranormal investigating is largely experimental and theoretical:  it works on the idea that electromagnetism is a common principle of our physical universe and the unknown physical universe of the spirit realm, it provides an opportunity to rule out localized E.M.F. pollution as the source of paranormal activity:  if activity occurs within the Faraday enclosure, and it cannot be rationally explained by any other devices within, then its origins are potentially paranormal.
