the material is magnetic.

bcz it is following it's principals of attraction and repulsion

Answer:

When the needle is repelled by one pole of the magnet, it swings around because unlike poles of the needle and the magnet face each other. Hence, north pole of the needle will face the south pole of the magnet and vice versa. Thus, we can say that only repulsion by the other magnet is a sure test of a magnet.
