Question

a freely suspended bar magnet always shows north-south direction.

Answer 1

Answer:

A freely suspended magnet always points in the north south direction as earth behaves as large magnet. the north pole of the earth's magnet attracts the south pole of the magnet and vice versa. Note: The north pole of earth's magnet is in geographical south because it attracts the south pole of the suspended magnet.

Answer 2

Answer:

The earth itself behaves like a magnet . Therefore a freely suspended magnet always points towards in the north-south direction because the north pole of the suspended magnet attracts the south pole of the earth's magnet which is the geographical north pole of the earth.

SIMPLER WORDS:

If freely suspended, one pole will point toward the north. The two poles are thus named the north magnetic pole and the south magnetic pole (or more properly, north-seeking and south-seeking poles, for the attractions in those directions).

Hope this helps!
