If we consider the molecules of iron to be polarized, we can explain magnetism and magnetic induction as follows. A magnet is a piece of iron composed of molecular magnets which lie partly or wholly in a uniform direction. When a piece of iron is in a neutral condition, not polarized, the molecular magnets of which it is composed have no uniform direction, their positions being determined by the mutual action they have upon one another. When, however, a magnet is brought near, their mutual action is overpowered by the greater force of the magnet, they assume parallel directions, and the iron becomes a magnet.
