Answer: Magnetic south pole.
- A Magnetic north pole
- B Magnetic south pole
- C No magnetic pole
- D Varies by location
Correct answer: B. Magnetic south pole
Explanation: Earth's geographic north pole is near a magnetic south pole (as compass north points toward it). By convention, the pole near geographic north is sometimes called the magnetic north geographic pole.
Magnetic field lines form closed loops: outside the bar magnet they run from the N pole to the S pole; inside, they continue from S back to N, so the lines never start or end anywhere.
Concept context
Bar magnets, Earth's magnetism, and how different materials respond to an external magnetic field - diamagnetic, paramagnetic, and ferromagnetic behaviour.
