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?

• A. Horizontal at the equator
• B. Vertical at the poles
• C. Horizontal at the poles
• D. Vertical at the equator

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.

Answer 1

The Correct Option is A, B

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.
