Magnetite is strongly magnetic. It was used by the ancient Chinese to make the first magnetic compasses. The chemical formula is Fe 3 O 4, commonly called ferrousferric oxide, and is valuable as an iron ore. Magnetite reacts with oxygen to produce hematite, another iron ore. In crystalline form magnetite is usually octahedral.
