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

In electrical engineering, electromagnetic shielding is the practice of reducing or redirecting the electromagnetic field in a space with barriers made of conductive or magnetic materials. It is typic

…currents generated from external or internal electromagnetic fields, and thus they block a large amount of the electromagnetic interference (see also electromagnetic shielding). They provide less attenuation of outgoing transmissions than incoming: they can block electromagnetic pulse (EMP) waves from natural phenomena very…
