Answer: south pole to north pole.
- A south pole to north pole
- B north pole to south pole
- C east side to west
- D centre outward
Correct answer: A. south pole to north pole
Explanation: By convention the dipole moment points from the south pole to the north pole inside the magnet.
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.
