### Electrostatic Shielding | Harvard Natural Sciences Lecture ...

However, shielding the outside can be accomplished by grounding the conductor. This allows charges to flow (from ground) onto the conductor, producing an electric field opposite to that of the charge inside the hollow conductor. The conductor then acts like an electrostatic shield as a result of the superposition of the two fields.

When the textbooks try to show why the electric field inside a conductor is zero they say let us put our conductor in an electric field. What happens then is that there will be an induced surface charge density which consequently induces an electric field within the conductor such that the total electric field within the conductor will be zero.
