Question:
Which of the following statements is/are correct regarding the magnetic field lines of the Earth, at the magnetic poles and the magnetic equator?
Which of the following statements is/are correct regarding the magnetic field lines of the Earth, at the magnetic poles and the magnetic equator?
Show Hint
At the Earth's magnetic poles, the magnetic field lines are vertical, while at the equator, they are horizontal. This is fundamental to understanding Earth's magnetic field structure.

- Horizontal at the equator
- Vertical at the poles
- Horizontal at the poles
- Vertical at the equator
Hide Solution
Verified By Collegedunia
The Correct Option is A, B
Solution and Explanation
Step 1: Understanding the Behavior of Earth's Magnetic Field Lines
The Earth's magnetic field lines behave differently at the poles and the equator:
At the magnetic equator: The magnetic field lines are horizontal and run parallel to the Earth's surface.
At the magnetic poles: The magnetic field lines are vertical and converge toward or diverge from the Earth's surface.
Step 2: Conclusion
Statement (A) is correct: Magnetic field lines are horizontal at the equator.
Statement (B) is correct: Magnetic field lines are vertical at the poles.
Statement (C) is incorrect: Field lines are not horizontal at the poles.
Statement (D) is incorrect: Field lines are not vertical at the equator.
