Assertion (A): Compass needle points the magnetic north-south direction.
Reason (R): The magnetic meridian of the earth merges with the axis of rotation of earth.
- a)Both A and R are true and R is the correct explanation of A
- b)Both A and R are true but R is NOT the correct explanation of A
- c)A is true but R is false
- d)A is false and R is true
Correct answer is option 'D'. Can you explain this answer?

Directions: In the following questions, A statement of Assertion (A) ...
Compass needle points the magnetic north-south direction. So the assertion is true. Earth’s magnetic meridian is along its axis through magnetic north-south direction. Earth’s axis of rotation is along its geographic north-south direction. The angle between these two axes is 11.3°. Hence, the reason is also false.

Assertion and Reasoning
• Assertion (A): Compass needle points the magnetic north-south direction.
• Reason (R): The magnetic meridian of the earth merges with the axis of rotation of the earth.
Explanation:
• The magnetic force of the earth is due to the movement of molten iron and nickel in the outer core of the earth. The flow of these metals generates an electric current, which in turn generates a magnetic field around the earth.
• The magnetic field of the earth is not uniform but is tilted at an angle of approximately 11.5 degrees to the earth's rotational axis.
• The point where the magnetic field of the earth is vertical to the ground is called the magnetic north pole and the opposite direction is the magnetic south pole.
• The compass needle aligns itself with the magnetic field of the earth and points towards the magnetic north-south direction.
• The magnetic meridian is the imaginary line passing through the magnetic poles of the earth. It is not the same as the geographical meridian, which passes through the geographical poles.
• The magnetic meridian and the geographical meridian are not parallel to each other. They intersect each other at an angle called magnetic declination.
• The magnetic meridian of the earth does not merge with the axis of rotation of the earth. The axis of rotation of the earth passes through its geographical poles.
Conclusion:
• Therefore, Assertion (A) is false and Reason (R) is true.
• Assertion (A): Compass needle points the magnetic north-south direction.
• Reason (R): The magnetic meridian of the earth merges with the axis of rotation of the earth.
