Answer 2

Explanation:

We will suspend the magnetic needle freely from a thread. It will align itself with the earth's field. Now, we know the north pole of the needle. We will bring north pole of the needle near the ends of the horseshoe magnet. The pole which will repel it will be the north pole, and the other will be the south pole.
