This model shows the electrification of a body and the transfer of **electric charge**. Electric charge can move the metal ball between the two metal mugs. The **plastic insulator gets charged by rubbing**. The electric charge is transferred to the metal plate and then to the mug by touching it. Since the **mug is charged** and the **metal ball is not**, both objects are **attracted** to each other.
The **electrostatic force** of attraction acts between the charged and uncharged objects. When the ball is touching the charged wall of the mug, a part of the charge is **transmitted** onto the surface of the ball. After charging, the ball is **repulsed** from the charged mug and draws to the uncharged one.
