The reason a Faraday cage protects sensitive equipment is best described by

  • A.the reflection of the field by the polished surface of the metal
  • B.the earthing of the cage
  • C.the vanishing of the field within a closed conductor
  • D.the absorption of the incident field by eddy currents in the metal

Answer: C

Charge redistributes on the conducting shell so that the interior field cancels, and Gauss's law guarantees the redistribution is always possible. Earthing helps with the external field but the interior cancellation does not depend on it.
