Magnetic Mineral an overview ScienceDirect Topics

András Kovács, Rafal E. Dunin-Borkowski, in Handbook of Magnetic Materials, 2018. 5.4 Oxidation and Thermomagnetic Properties of Pseudo-Single-Domain Magnetite Particles. Magnetic minerals in rocks record the direction and intensity of the Earth's ambient magnetic field during formation, thereby providing information about past tectonic plate motion. In order to reliably interpret

Magnetite: The mineral Magnetite information and pictures

Magnetite is an important ore of iron. Well formed crystals are popular among mineral collectors, and the magnetic Lodestone variety is frequently sold in hobby shops to amateur collectors. Magnetite is also of significant interest to the science community due to its strong magnetic properties.

Magnetite Wikipedia

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of
