Interesting Facts:

• The magnetic field lines always flow from the north pole to the south pole (outside the magnet).
• Inside the magnet, field lines flow from the south pole to the north pole.
• The field is strongest at the magnet’s poles.

Activities for Learning:

1. Rotate the entire scene using the “Scene rotation” slider. Notice how the field lines remain the same pattern in the canvas coordinate system, but you see them turning visually.
2. Drag the compass in the rotated view and observe how it aligns with the magnetic field.
3. Adjust the number of field lines using the slider and see how it affects the visual representation of the field.
4. Press “Play” to see the compass move (if outside the magnet, it moves opposite to the field direction).
5. Place the compass inside the magnet and observe the reversed needle direction.

Suggestions for Further Exploration:

• Inquiry Activities: Challenge students to measure or compare how the compass behaves inside vs. outside the magnet, or at different rotations.
