Magnetic properties of minerals are defined as follows: Ferromagnetism describes strong attraction to magnetic fields. This property is exhibited in few minerals, notably Magnetite and Pyrrhotite . Paramagnetism is weak attraction to
Abstract. All materials respond in some way to a magnetic field so that all minerals have magnetic properties. Minerals which contain no ions with uncompensated spins (e.g., an absence of, notably, the transition series elements) are diamagnetic.Those containing transition elements in low concentrations are paramagnetic.The ratio of the magnetic susceptibilities of these two
Magnetic properties of minerals. The intrinsic magnetic properties are those that are determined by the species of magnetic atom in the compound and the arrangement of the atoms in space in the crystal lattice. The minerals of the Earth's crust have a ferrimagnetic spin structure. The properties of the magnetic structure may be described in ...

The Magnetic Minerals are few, but the property is important because of this fact. Once a specimen is established as magnetic, identification becomes a rather routine exercise. The mineral magnetite is named after this characteristic.. Magnetism occurs (most often) when there is an imbalance in the structural arrangement of the iron ions.
