====Faraday cage====
In his work on static electricity, [[Faraday's ice pail experiment]] demonstrated that the charge resided only on the exterior of a charged conductor, and exterior charge had no influence on anything enclosed within a conductor. This is because the exterior charges redistribute such that the interior fields emanating from them cancel one another. This shielding effect is used in what is now known as a [[Faraday cage]].<ref name="Pioneers"/> In January 1836, Faraday had put a wooden frame, 12&nbsp;ft square, on four glass supports and added paper walls and wire mesh. He then stepped inside and electrified it. When he stepped out of his electrified cage, Faraday had shown that electricity was a force, not an imponderable fluid as was believed at the time.<ref name="Field"/>
