dielectric (Physics Dictionary)

dielectric : An electrical insulator that can be polarized by an applied electric field. When a dielectric material is placed in an electric field, electric charges do not flow through the material as they would in a conductor but only shift slightly from their equilibrium positions, with positive charges displaced in the direction of the field’s flow and negative charges displaced in the opposite direction; this creates an internal electric field that reduces the larger field within the dielectric material.
