Force, Motion, and Energy Quiz

The picture shows some ring magnets on a pencil. A student pushed the magnets together, but they came apart as soon as the student let go. Why did the magnets stay apart from each other?

• Magnets are too weak to stay together for a long time.

• Materials that make up the magnets are not magnetic.

• Same poles of the magnets are facing each other.

• The shape of the pencil stops the force of the magnets.
