Magnetite

  

Strongly magnetic, this mineral is also known as “lodestone”. It is a common accessory mineral and can be found in banded iron formations. It is named for the locality Magnesia, Greece. A fable ascribes its name to a shepherd named Magnes, who first discovered the mineral on Mount Ida after noticing that the nails of his shoes and the iron ferrule of his staff adhered to the ground.
