Suppose we have a positively charged object near a conductor. What happens to the charge distribution of the conductor when we bring an identical positively charged object near to the other side of the conductor? The situation is pictured to the right.

• Electrons in an insulator are tightly bound to the nucleus.
• Charges cannot move freely through an insulator.

• An explanation for whether it is possible to charge a pair of insulators using induction.

• We are talking about pure insulators, so we can use the facts listed.
• By pure insulators, we mean there are no electrons on the surface that are not bound to any nuclei.
• By induction, we mean the process shown in the figure to the right.

• We can model the atoms in an insulator as little ovals, that show when one side of the atom is more positive or negative than the other side. When ovals are not shown, this will just mean the atoms are not polarized.
• We can use a similar diagram as the induction figure in the notes, since we assume it is the same process.
