If a bar magnet is hung from a string, in which direction does its north pole point?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. North.
When a bar magnet is hung from a string, its north pole points towards the Earth's geographic north pole. This is because the Earth acts like a magnet, with its magnetic south pole near the geographic north pole.
Explanation
- The magnet swings for a while, and eventually comes to rest in a north-south direction.
- The Earth acts like a giant magnet, with its magnetic south pole near the geographic north pole.
- The north pole of a freely suspended magnet is attracted to the Earth's magnetic south pole.
