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

Step 1: Treat the Earth as a magnet.
The Earth behaves like a huge bar magnet sitting near its centre, with a field spreading all around the planet.

Step 2: Recall the field direction rule.
Outside any magnet the field lines run from the magnet's north pole to its south pole.

Step 3: Place the imaginary magnet.
For the Earth, the bar magnet's north end sits near the geographic south, so the external field comes out near the geographic south.

Step 4: Trace the field on the surface.
The field therefore points roughly from the geographic south towards the geographic north over the Earth's surface.

Step 5: Match the option.
This matches the choice geographic south to the north.

Step 6: Conclude.
The Earth's magnetic field points approximately from geographic south to north.
\[ \boxed{\text{Geographic south to the north}} \]
