Answer: 0°.
- A 0°
- B 30°
- C 45°
- D 90°
Correct answer: A. 0°
Explanation: At the magnetic equator the Earth field is horizontal, so the dip angle is 0°.
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.
