Detailed explanation-1: -Using a Compass to Identify Magnet North Pole Take a magnetic compass and place it close to but not touching your magnet. Watch carefully at where the compass needle points. The point that normally points to the north pole of Earth should point to one end of the magnet.
Detailed explanation-2: -How would you find out near which end is its north pole located? SOLUTION: A freely suspended bar magnet always comes to rest in the North-South direction. The geographical North facing end of the magnet is its north pole and the geographical south facing end is its South pole.
Detailed explanation-3: -So when the compass is placed near the north pole of a bar magnet, it points away from it. When kept near the south pole, the compass points towards the south pole of the bar magnet.
