Magnetic Properties: Mineral Properties - The Mineral

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 magnetic fields. The attraction is

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.
