Magnetite - Wikipedia Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 2+ Fe 3+ 2 O 4 It is one of the oxides of iron, and is ferrimagnetic; [6] it is attracted to a magnet and can be magnetized to become a permanent magnet itself
Magnetite Lodestone | Mineral Photos, Uses, Properties Normal magnetite is attracted to a magnet, but some specimens are automagnetized and have the ability to attract small pieces of iron, small pieces of magnetite, and other magnetic objects This form of magnetite, known as "lodestone," was man's first encounter with the property of magnetism
Magnetite | Common Minerals Magnetite is a black, opaque, magnetic mineral that leaves a black streak when rubbed across a hard rough surface It is one of the most abundant metal oxides, and its crystal structure contains both the ferrous (Fe+2) and ferric (Fe+3) forms of iron ions
Magnetite : Properties, Occurrence, Formation, Deposits - Geology Science Magnetite is a naturally occurring mineral that is one of the most common iron ores and is widely distributed throughout the world It is a black, metallic-looking mineral with a distinctive magnetic property, hence its name
Magnetite: Mineral information, data and localities. - mindat. org Magnetite is an important iron ore, along with hematite It is usually easily distinguished by being strongly magnetic, with black octahedral crystals Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007)
Magnetite: Ultimate Guide to Magnetite (What It Is and Where to Find It . . . Magnetite is an iron mineral, specifically, it’s an oxidized form of a balanced blend of iron ions It contains both divalent (Fe²+) ions and trivalent (Fe³+) ions It’s most commonly seen as octahedral crystals with a black color, although some may take on a brownish tinge
Magnetite | Magnetic Properties, Iron Oxide, Magnetism | Britannica All are magnetic, although franklinite and jacobsite are only weakly so; magnetite, which frequently has distinct north and south poles, has been known for this property since about 500 bc For detailed physical properties, see oxide mineral (table)
Magnetite: Meanings, Properties, Facts and More Magnetite is a mineral with magnetic properties It’s an iron oxide, and its chemical composition is Fe3O4 It has a black or dark brownish-red hue and often occurs in crystalline form as well as massive granular aggregates of small crystals
The Mineral magnetite - The Mineral and Gemstone Kingdom 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 – Virtual Museum of Molecules and Minerals Magnetite is one of the most ubiquitous of all minerals, occurring in a wide variety of igneous, metamorphic, and sedimentary rocks It usually occurs as small disseminated crystals or grains composing not more than 1% of the rock in which it is found
