How Does A Faraday Cage Work

Posted on November 22, 2010 by Draqos

An important device in applied electromagnetic study and research and the applied science of the same field is the Faraday cage. The Faraday cage is a device that cancels out all electrostatic fields within the space that it encloses. Typically it is a metallic enclosure or cage that eliminates all electric fields of static nature by rearranging the charges within itself to such an extent such that there is no electric field. This is an intrinsic property of conductors and has been used ever since it was first discovered in the early 19th century.

What Is A Faraday Cage?

Posted on November 3, 2010 by Draqos

Faraday cages, so named after the great physicist Michael Faraday are typically metal enclosures, either solid or mesh like structures that are designed to block static electric fields. The first Faraday cage was built in 1836 by Michael Faraday.

Faraday cages are built on the principle that the electric field within a conductor is zero. This is due to the intrinsic property of all metals and conductors, which makes them redistribute their charges in a manner that will inevitably block all the external static electric fields. The concept of zero electric field within a conductor forms the basis of several electromagnetic research fields and this is precisely where faraday cages are extensively used.

How Can I Make A Faraday Cage

Posted on November 3, 2010 by Draqos

Faraday cages are nothing but metallic conductors that, when used to cover an area or an electric device, make that area free of any electric fields. This happens due to the characteristic property of conductors which lets them retain the charge on the surface and keep the field inside at a total zero.
While they are mainly used in labs and industries, Faraday cages are nevertheless fun to play around with or have one handy at home. There is nothing very technical about making one and anyone can create a Faraday cage out of the odd metallic materials that is found at home. If there is a long string of metallic wire that is easily available, a cage similar to the original one that Michael Faraday had made can be easily achieved with a simple knitting skill that would result in a mesh like structure with the metallic string.

History of Faraday Cages

Posted on November 3, 2010 by Draqos

The idea that led to the development of a Faraday cage sprung up in 1836 when Michael Faraday, a well known British physics scientist observed that the charge on a metallic conductor redistributed itself in a manner that enabled it to maintain a field that is zero on the inside and hold the charge on the surface.
Since then, the Faraday cage was worked with in various aspects and has undergone several transformations to be the device of extensive applications today. The first experiment that was designed to prove the working of the Faraday cage was rather large scale and was built by Michael Faraday himself.
