One way to make a compass is to stick a magnetized needle into a piece of cork and ficat it in a glass bowl full of water. The needie will align itself with the horizontal component of the Earth's magnetic field. Since the north pole of this compass is attracted northward, will the needle float toward the north side of the bowl? Defend your answer.
