GEOLOGY

Detailed explanation-1: -(1) A freely suspended magnet always points in the north-south direction. (2) Like magnetic poles repel each other; unlike magnetic poles attract each other. If a bar magnet is freely suspended, it will swing until its one end points towards the north pole of the earth and the other towards the south pole of the earth.

Detailed explanation-2: -A freely suspended magnet always rest in north-south direction because the north-pole of the magnet lies in the geographic north direction and the south pole of the magnet lies in the geographic south direction. So it aligns itself in N-S direction. As unlike poles attract and like poles repel.

Detailed explanation-3: -Importance of Magnetic Poles One end of any bar magnet will always want to point north if it is freely suspended. This is called the north-seeking pole of the magnet, or simply the north pole.

Detailed explanation-4: -Solution: A freely suspended magnet always rests in the north-south direction because the magnetic south pole of the earth lies in the geographic north direction and the magnetic north pole of the earth lies in the geographical south direction.

Detailed explanation-5: -When a bar magnet is left to move freely, it will swing till its one end move towards the north pole of the earth and the other end move towards the South pole of the earth. As the unlike poles attract each other and like poles repel each other, the magnet always aligns itself in the North South direction.
