Question

Oran uses a ball, a bar magnet, and a compass to create a model of Earth’s magnetic field. How could he best use these materials? He could glue the compass to the ball so the needle points to the top of the ball, and move the bar magnet to show how the compass direction changes. He could glue the compass to the ball so the needle points to the bottom of the ball, and move the bar magnet to show how the compass direction changes.
