According to Greek legend magnetism was first discovered by a shepherd named Megnes, who lived in Megnesia, Greece. Megnes was herding his sheep through the mountains. Suddenly he noticed the ferrule of his stick and nails in his sandals got stuck to a rock. The iron in his stick and nails had become attracted to the magnetic rock. The stone was named as magnetite, after the name of the shepherd or the country it was found in. It was also known as loadstone because of its attractive properties.

Properties of Magnets

A magnet attracts magnetic materials towards itself.
A freely suspended bar magnet always aligns in the north-south direction.
Unlike poles attract each other and like poles repel each other.
A magnet with a single pole does not exist. If a magnet is cut into two pieces each piece will behave like an independent magnet, with a north pole and a south pole.
When a bar magnet is rubbed over an iron bar, it changes the iron bar into a magnet.
