When we take a lump of lodestone, which is an iron ore, and place it near a piece of iron, the lodestone will attract the iron. The iron in its turn will then attract particles of iron. The iron is called an artificial magnet. Thus iron and steel when brought in contact with the lodestone have the property of becoming magnetized and attracting iron. Magnets made of soft iron lose their magnetism very easily and are called temporary magnets; while hard iron and steel retain their magnetism and are called permanent magnets.
