DESCRIPTION
The pendulum with an insulated handle was convenient for electrostatic tests. When in the vicinity of a charged body, the pith ball becomes polarized in such a way that unlike charge is shifted in the direction of the charged body and like charge in the opposite direction. The net effect is an attraction toward the charged body. If the pith ball is allowed to touch the charged body, some of that charge will transfer to the skin of the pith ball, overcome the dielectric attraction and cause the pith ball to recede. That transferred charge remains on the skin of the pith ball because it is an insulator and does not conduct.Dati Catalografici
