Magnets

Kim pushed the magnets together, but they came apart as soon as she let go. Why do the magnets repel each other?

• The pencil stops the force of the magnets.

• The magnets are not strong enough to stay together.

• The same poles of the magnets are facing each other.

• The amount of air space between the magnets stops the magnetic force.

Matt has two bar magnets. When he holds the ends of the magnets together, one end of the magnet is attracted to the other end of the magnet, but not the middle of the magnet. How can Matt explain the reaction of the magnets?

• The ends of both magnets are north poles.

• The middle of the magnet is not working correctly.

• The magnetic forces of each magnet are strongest at the poles.

• The ends of both magnets were south poles.

Dustin is doing an experiment on magnetism. He observes that a piece of paper is not pulled toward a magnet. He wonders why a magnet is able to stick to paper on a magnetic refrigerator. Which statement best explains why this can happen?

• The magnet repels paper.

• The paper contains nickel, iron, or cobalt.

• The paper has been rubbed many times with a magnet.

• The magnet is attracted to the refrigerator metal through the paper.
