FARADAY CAGE

The Faraday cage is an earthed metallic wire or gauze screen enclosing electrical equipment to shield it from the influence of external electric fields. The principle, put forward by Michael Faraday, is that within a conductor there is no charge, and this has been proved correct. The principle is used to make metal jump suits to be worn by electrical engineers working on high tension electricity cables.
