Question

The earth behaves as a magnet with the magnetic field pointing approximately from the

• A. Geographic south to the north
• B. Geographic north to the south
• C. Geographic east to the north
• D. Geographic west to the north

Hint:

The Earth acts like a giant bar magnet placed near its centre, producing a magnetic field that surrounds the planet.

Answer 1

The Correct Option is A

Concept:
The Earth acts like a giant bar magnet placed near its centre, producing a magnetic field that surrounds the planet.

Step 1:
By convention, the direction of a magnetic field is taken from the south pole to the north pole of the magnet inside, and from north to south outside. For the Earth's internal dipole the field points approximately from the geographic south to the geographic north.

Step 2:
This orientation is why a freely suspended compass needle aligns along the north-south line, with its north-seeking end pointing toward the geographic north.

Answer: Option (1) — Geographic south to the north.
