3rd Grade - Marvelous Magnets (Magnetic Energy, Magnets)

The picture shows some ring-shaped magnets on a pencil. 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.
