Description

Charges redistribute themselves in a conductor under the influence of an external electrostatic field. For example, a positive charge close to a neutral conductor will attract the negative charges in the conductor to the closest surface, leaving the opposite side with a positive charge.

With this principle, an object A can be charged if it is grounded while another charged object B is held close. The induction pushes the charges in the ground. Disconnecting the ground and taking away the charged object B, object A will be left with an opposite charge. The electrophorus works on that principle.
