I read that charge by induction precedes force of attraction between a charged body and a neutral one. That is, the nearer end of the body gets oppositely charged when a charged body is brought closer to the neutral one. Since we now have 2 oppositely charged objects (object parts) closely spaced, the force of attraction takes of place. Now my question is about a negatively charged plastic rod brought closer to a neutral plastic rod. The 2 attract each other. How is charge by induction taking place in the neutral rod. The neutral rod, being an insulator does not have free electrons - insulators do not conduct because they do not have free electrons - then, how is positve charge formed on the neutral one at the nearer end to the negatively charged plastic rod?
