• Increases
• Decreases
• Stays the Same

If you cut a magnet in half, what happens to the poles?

• One half gets the North Pole, the other half gets the South Pole
• Both halves get only a North Pole
• Both halves get only a South Pole
• Both halves get a North pole and a South Pole

What is responsible for the Magnetic Field around Earth?

How does distance affect magnetism?

• distance does not affect the strength of magnetism.

• magnetic force is stronger the further away objects are to each other.

• magnetic force is stronger the closer objects are to each other.

• magnetic force is weakest the closer objects are to each other.
