Section 9.3: Magnetism and Magnetic Fields
Diagram-Based Answers (Typical labeling):
- North pole red coloring, South pole blue or white.
- Magnetic field lines: North → South externally, South → North internally.
- Neutral points: Locations where magnetic fields cancel out (e.g., between two like poles facing each other).
True or False Correction:
- False – Magnets attract magnetic materials (iron, steel, nickel, cobalt), not all metals (e.g., aluminum, copper are non-magnetic).
- True – The Earth’s geographic North pole is actually a magnetic South pole.
- False – If you cut a bar magnet in half, you get two smaller magnets, each with a N and S pole.
