Question

A compass needle points north
when you let it move freely
Why do scientists think this happens​

Answer 1

Answer:

A compass needle points north because the north pole of the magnet inside it is attracted to the south pole of Earth's built-in magnet.

Answer 2

Explanation:

A compass points north because all magnets have two poles , a north pole and a south pole, and the north pole of one magnet is attracted to the south pole of another magnet. (You may have seen this demonstrated by a pair of simple bar magnets or refrigerator magnets pushed end to end.)
