MS-PS2-3 · Why do magnets stick to some metals but not others?
Driving Question: What patterns exist in magnetic fields?
1. Click on the canvas to place a compass needle — it aligns with the field.
2. Drag magnets to move them. Click Flip to reverse polarity.
3. Test materials: click Iron, Copper, Wood, Nickel to see if they're attracted.
4. Notice: field lines always go from N (red) to S (blue).

If you bring two N poles together, what will happen to the field lines between them? Draw your prediction.
Place both magnets with N poles facing each other. Place compasses between them. What pattern do you see?
Why do magnets attract iron but not copper? Use the concept of ferromagnetism and electron alignment to explain.
