Q1. Consider the following statements: 1.The axis of the earth’s magnetic field is inclined at 23 and half 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.The earth’s magnetic equator passes through Thumba in South India. Which of the statements given above is/are correct?
Explanation
Statement 1 is incorrect: The Earth’s magnetic axis is tilted at approximately 11 degrees relative to its geographic axis (the axis around which the Earth rotates). The 23.5-degree tilt refers to the Earth’s rotational axis relative to its orbit around the Sun, which is responsible for the seasons, not the magnetic field.
Statement 2 is correct: The North Magnetic Pole is currently located in the Arctic region of Northern Canada, specifically on Ellesmere Island. The magnetic poles are not fixed and move over time due to changes in the Earth’s magnetic field.
Statement 3 is correct: The magnetic equator is an imaginary line where the Earth’s magnetic field is entirely horizontal (no dip angle). The magnetic equator passes near Thumba in South India. The Thumba Equatorial Rocket Launching Station was established in this location due to its proximity to the magnetic equator.
