Explanation

Bar magnets are usually made of ferromagnetic materials, which are elements that can naturally have a magnetic field. Each end of a bar magnet is called a pole — one is north and the other south. When freely suspended, the magnet will align itself so that the end of its northern pole points towards the Earth’s magnetic north pole.
