Explain how distance affects the strength of the magnetic forces between two objects based on the image shown and how this is related to electric force and distance.

• The electrical force between the magnet and paper clips is only in effect when they are touching.

• The electrical force between the magnet and paper clips increases as the distance between them increases.

• The electrical force between the magnet and paper clips is not affected by distance.

• The electrical force between the magnet and paper clips increases as the distance between them decreases.

You loaned your favorite magnet to a neighbor to find a lost metal treasure in their backyard. The friend drops and breaks your magnet. What is the best explanation of what will happen to the magnetic force in your broken pieces?

• The pieces will either be only the North pole or South pole and become monopole magnets.

• The pieces will be smaller magnets having both a North or South pole.

• The magnet will become electrified and can be used as an electromagnet.

• The magnet will no longer be magnetic because the electrons have lost their magnetic ability.
