Faraday cage. A Faraday cage or Faraday shield is an enclosure used to block some electromagnetic fields. A Faraday shield may be formed by a continuous covering of conductive material, or in the case of a Faraday cage, by a mesh of such materials. Faraday cages are named after scientist Michael Faraday, who first constructed one in 1836.

Enclosures can be pressurized with clean air or inert gas, displacing any hazardous substance. Arc-producing elements can be isolated from the atmosphere, by encapsulation in resin, immersion in oil, or similar. Heat-producing elements can be designed to limit their maximum temperature below the autoignition temperature of the material involved.
