Magnetism - Magnetic properties of matter | Britannica.com

Magnetism - Magnetic properties of matter: All matter exhibits magnetic properties when placed in an external magnetic field. Even substances like copper and aluminum that are not normally thought of as having magnetic properties are affected by the presence of a magnetic field such as that produced by either pole of a bar magnet. Depending on whether there is an attraction or repulsion by the ...

University of Minnesota's Mineral Pages: Calcite

From trade routes to conquest, the pageant of human history would have been very different without the magnetic properties of this non-descript black mineral. Many people assume that magnetite's name is derived from its magnetic properties, but the term 'magnet' actually comes from the mineral. 'Magnetite' was named after the Magnesia region of Thessaly, Greece, the home of the ...

Ilmenite exhibits a black streak similar to that of magnetite, while hematite's streak is red to reddish brown. Graphite. Graphite has a shiny metallic appearance and dark color so it may initially be confused with metallic hematite, but the two minerals' other properties easily distinguish them. Metallic varieties of hematite are much harder than graphite, and have a higher specific ...
