Facts about Magnets

The first magnets were known as magnetite or lodestone.

 
     
It is said that a Cretan shepherd called Magnes first noticed lodestone when the iron-tipped end of his crook was pulled down when he passed a certain rock.

 
     
The ancient Greek scientist, Archimedes of the "Eureka!" fame is believed to have used lodestone to pull nails from enemy ships, which then sank.

 
     
Sailors used lodestone to help them navigate. They had found that when a piece of magnetite was suspended from a thread it came to rest in a North-South direction.
