The bar magnet suspended freely aligns itself in the north-south directions. Why?

Text Solution

Verified by Experts

A freely-suspended bar magnet aligns itself in north-south direction because the earth acts like a huge bar magnet with its North Pole facing towards geographic South Pole and magnetic South Pole towards geographic North Pole. The North Pole of the suspended bar magnet gets attracted towards magnetic South Pole of the earth, i.e., the geographic North Pole.
