Faraday Suit
A Faraday cage or Faraday shield is an enclosure used to block 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 invented them in 1836. A Faraday cage operates because an external electrical field causes the electric charges within the cage's conducting material to be distributed so that they cancel the field's effect in the cage's interior. This phenomenon is used to protect sensitive electronic equipment (for example RF receivers) from external radio frequency interference (RFI) often during testing or alignment of the device. They are also used to protect people and equipment against actual electric currents such as lightning strikes and electrostatic discharges, since the enclosing cage conducts current around the outside of the enclosed space and none passes through the interior.

Cage De Faraday
A cage is an enclosure often made of mesh, bars, or wires, used to confine, contain or protect something or someone. A cage can serve many purposes, including keeping an animal or person in captivity, capturing an animal or person, and displaying an animal at a zoo. Construction Since a cage is usually intended to hold living beings, at least some part of its structure must be such as to allow for the entry of light and air. Thus some cages may be made with bars spaced too closely together for the intended captive to slip between them, or with windows covered by a mesh of some sort. Animal cages Cages are often used to confine animals, and some are specially designed to fit a certain species of animal. One or more birds, rodents, reptiles, and even larger animals of certain breeds are sometimes confined in a cage as pets. Animal cages have been a part of human culture since ancient times. For example, an Ancient Greek vase dated to 490 B.C. depicts a boy holding a possibly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
