An expert explains electricity with three demonstrations. In the first demonstration, a student shows that when he rubs rods with a cloth, the rods become charged with static electricity. The rods attract or repel each other as a result of the electrical force. The expert and the student discuss static electricity in terms of electrons moving from the cloth to the rod. In the second demonstration, the student then explains current electricity by rubbing his feet on carpet and then touching metal. A final demonstration shows that electrical current flowing through a wire creates a magnetic field.
