Document Summary
Faraday cage and shields the internal space from any electric fields from the outside. Faraday cage does not shield electric field produced by charge within. There are no field lines in a conductor. It can only shields the electric field from the outside , but not on the inside. The conductor can have a field line in it for a moment. But then the field line will disappear since the free electrons more in the opposite direction from the field lines. If you ground the than this electrons from the ground will. S come up and neutralize positive charges the. The charges can go through the faraday cage but it cannot be inside the. The only way the charges can be inside the faraday cage is if there is a place for it to leak in. Stored in the electric field . there is energy to move the test charge q. The force depends on if the distance you move.
