Answer: Inclination (dip).
- A Declination
- B Inclination (dip)
- C Latitude
- D Azimuth
Correct answer: B. Inclination (dip)
Explanation: Magnetic inclination, or dip, is the angle the Earth's magnetic field makes with the horizontal plane. It is 0° at the magnetic equator and 90° at the magnetic poles.
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.
