Transcript of Magnetism

History of the invisible force
There is a legend which states that the first magnet ever found was discovered by a Greek shepherd named Magnes. It is said that he found the magnet when it was attracted towards his shoe nails and the tip of his staff. This is when the strange rock was named Magnes Lithos, meaning a natural magnet.

About 1100 years after the discovery, the chinese observed that when a piece of magnetite was suspended freely it always rested in the north south position. This discovery helped sailors, so it was name the leading stone or the lodestone.
