Magnetite is a form of iron oxide, Fe 3 O 4, which possesses uniquely iron in both the Fe 2+ and Fe 3+ oxidation states. Bearing the form of an inverse spinel, it's magnetic properties are highly valued. Addition of magnetite to soil is advantageous as it can later be removed easily by using magnets. It can occur naturally in soil, or be added as a soil treatment agent.

Magnetite is an oxide of iron (as is hematite).It is not a component of ordinary rust, although it can form as iron oxidizes in a dry environment. When you see sparks from welding operations or from iron striking a hard surface (as when it is held against a spinning grinder), the sparks are due to the rapid (and exothermic) oxidation of tiny particles of iron into magnetite.
