Roman is using a bar magnet in an experiment to determine how its magnetic field lines look. He accidently drops the magnet, breaking it in two. He picks up both pieces and modifies his experiment to determine what happened to the magnet when he dropped it. Which of the following statements may Roman find to be true during his experiment? Choose the two that apply.

1) both pieces becomes a magnet.

2) both has north and south pole.

Explanation:

When the magnet is broken into two pieces, both pieces of magnets act as a real magnet which makes magnetic field around them. These newly made magnets have their own north and south pole. When the north pole of both magnets come close together so they repel each other. The reason is that when they are present in joint form, they have a single north and south pole but when they are broken into pieces both have separate north and south pole.
