Can insulators be charged by induction method?

Expert Answer:

Even though the charges are not free to travel throughout the material, insulators can be charged by induction. A large charge nearby—not touching—will induce an opposite charge on the surface of the insulator. As shown in Figure 3 , the negative and positive charges of the molecules are displaced slightly. This realignment of charges in the insulator produces an effective induced charge.
