Electrostatic field lines around two point charges and a cylinder (Faraday cage). The left point is charged to -30,000 volts while the right point has a potential of +30,000 volts. Of special importance is the lack of fields showing inside the cylinder,which acts as a Faraday cage,shielding the enclosed area from any external electrical fields. This is the classic case of no electrical fields inside an electrical conductor. Part of a series showing different charging conditions. The electric fields are shown by placing the two charged objects in a pan filled with cooking oil and pepper flakes,which align in the electric field,allowing visualization of the field | |
