    To become a lodestone, magnetite must be magnetized. regular magnetite is not formed magnetic, and in fact, most magnetite cannot be magnetized at all. in order for magnetite to become magnetized, it must have a certain crystal structure and chemical composition. lodestone is largely formed of magnetite, but it also has inclusions of maghemite oxidized magnetite and other metal ion impurities. these impurities and inclusions cause the crystal structure of the magnetite to be inhomogeneous and allows the mineral to resist demagnetization once it has been magnetized.
