a strong magnet attracts a paper clip to itself with a certain force. Does the paper clip exert a force on the strong magnet? If so, why not? If so, does it exert as much force on the magnet as the magnet exerts on it?
Newtons Third Law: Forces are always in pairs.
The forces they exert on each other are equal and opposite. That is an example of Newton's third law.
