A circuit that allows current to flow is

A circuit that does not allow current to flow is

Why is this happening?

• The child's hair and the balloon have opposite charges

• The balloon is magnetic

• Positive charges left the balloon and went to the child's hair

• Protons travelled from the child's hair to the balloon
