WebOct 25, 2024 · Magnetite, the only mineral that exhibits strong or obvious magnetism, has a magnetic-susceptibility rating of 20. While trace magnetism exists in many minerals, only about 20 exhibit significant magnetic susceptibility. All contain iron, either as their sole cation or part of a compound cation. WebMagnetite. Magnetite is an oxide mineral with structural formula [Fe2+ (Fe3+)2O4] having the spinel structure. Other minerals in the series include magnesioferrite [Mg2+ (Fe3+)2O4], franklinite [Zn2+ (Fe3+)2O4] and jacobsite [Mn2+ (Fe3+)2O4].
