Question

The Earth's magnetic field approximately ranges between:

• A. 250 and 650 microteslas
• B. 25 and 65 microteslas
• C. 2.5 and 6.5 microteslas
• D. 0.25 and 0.65 microteslas

Hint:

Typical surface magnetic field = 25–65 μT. Poles stronger, equator weaker.

Answer 1

The Correct Option is B

The Earth’s magnetic field at the surface varies between approximately 25 to 65 microteslas (μT) depending on location: - Strongest near the magnetic poles - Weakest near the equator
