:: MAGNETISM ::
Magnetism is the power of certain stones and metals to attract each other. According to legend, the discovery of magnetism occurred about 3000 years ago in an ancient Middle Eastern country called Magnesia.
One day, the story goes, a shepherd found it difficult to lift his iron-tipped staff from certain places on the ground. After investigating, he realized that he had difficulty only when the iron tip was on a certain type of dark stone. These stones were loadstones (sometimes spelled "lodestone") , which contain a kind of iron ore called magnetite.
Since magnetism became known, man has found out much about this power and devised many uses for it. With the aid of science, he has also learned to impart magnetism to certain metals which do not possess it naturally.
