Question
Consider the following statements :
1. The axis of the earth's magnetic field is inclined at 23V4° to the geographic axis of the earth.
2. The earth's magnetic pole in the northern hemisphere is located on a peninsula in northern Canada.
3. Earth's magnetic equator passes through Thumba in South India.
Which of the statements given above is/are correct?

3. Earth's magnetic equator passes through Thumba in South India.
Which of the statements given above is/are correct?
Answer: Option B
:
B
Ans. (b)
Explanation
An imaginary line joining the magnetic poles would be inclined by approximately 11-3° from the planet's axis of rotation. The axis of the earth is inclined to the plane of the ecliptic (the plane in which the earth orbits round the sun) at an angle of 66 V20, giving rise to different seasons and varying lengths of day and night. Earth rotates on its own axis, tilted at an angle of 23-4° every 23 hr. 56' giving rise to Day and Night.
