Short description: Artificial magnetic material
Hematine (also magnetic hematite, hemalyke or hemalike) is an artificial magnetic material.[1] Hematine is widely used in jewelry.[citation needed]
Although it is claimed by many that it is made from ground hematite or iron oxide mixed with a resin, analysis (of one object) has demonstrated it to be an entirely artificial compound, a barium-strontium ferrite.[2]
