• Magnet A (S-N) Magnet B (N-S) Magnet C (S-N)

• Magnet A (N-S) Magnet B (S-N) Magnet C (N-S)

• Magnet A (S-N) Magnet B (S-N) Magnet C (S-N)

Abigail is hiking in the woods and uses a compass to find her way. She notices that the compass needle always points in the North-South direction. Why does the compass needle align itself this way?

• Because of the gravitational pull of the Earth.

• Because it is attracted to the polar ice caps.

• Because of the influence of distant stars.

• Because the Earth generates a magnetic field that interacts with the needle.

Zoe and Abigail are holding magnets. If Zoe moves her magnet closer to Abigail's magnet, which of the following best describes what happens to the force of attraction between the magnets?

• A. It varies.

• B. It increases.

• C. It decreases.

• D. It stays the same.

James holds a positively charged balloon, while Aria holds a negatively charged balloon. They start off standing far apart, but then walk towards each other, bringing the balloons closer together. What happens to the force between the balloons?

• The attractive force becomes a repulsive force, which increases as the balloons move closer to each other

• The repulsive force becomes an attractive force, which increases as the balloons move closer to each other.

• The attractive force increases as the balloons move closer to each other.

• The repulsive force decreases as the balloons move closer to each other.
