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.
