Magnetite is the most magnetic of all the naturally occurring minerals on Earth, and these magnetic properties led to its use as an early form of magnetic compass. Magnetite reacts with oxygen to produce hematite, and the mineral pair forms a buffer that can control oxygen fugacity.

How Magnets Work Howstuffworks
Lodestone, a form of magnetite, is the strongest naturally-occurring magnet. It can attract small objects, like paper clips and staples. By the 12th century, people had discovered that they could use lodestone to magnetize pieces of iron, creating a compass. Repeatedly rubbing lodestone along an iron needle in one direction magnetized the needle.
