It is applied both to home appliances and medical devices. [1] Typical materials used for electromagnetic shielding include thin layer of metal, sheet metal, metal screen, and metal ...
Faraday cages cannot block stable or slowly varying magnetic fields, such as the Earth's magnetic field (a compass will still work inside one). To a large degree, however, they shield the interior from external electromagnetic radiation if the conductor is thick enough and any holes are significantly smaller than the wavelength of the
