Magnetic Hematite Vs. Hematite Mineralogy Geology | eHow

"Magnetizing" Hematite People might assume that magnetic hematite is simply "magnetized" hematite. True hematite, though ironcontaining, actually has a weak magnetic field because of the way its iron atoms are aligned. On the other hand, the mineral magnetite is highly magnetic, and many often erroneously assume it is magnetic hematite (the artificial material). Like true .
