iron ore called magnetite that is naturally magnetized by the earths

Ferromagnetism

2018-10-17 · Ferromagnetism Iron, nickel, cobalt and some of the rare earths (gadolinium, dysprosium) exhibit a unique magnetic behavior which is called ferromagnetism because iron (ferrum in Latin) is the most common and most dramatic example. Samarium and neodymium in alloys with cobalt have been used to fabricate very strong rare-earth magnets.

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....

What Are Natural Magnets? | Reference

It is a black mineral that is rich in magnetite. Magnetite is rich in oxidized iron, and iron generally permits the free flow of electrons through it. This makes magnetite such a powerful magnet that in some animals, such as pigeons, it is incorporated into their brains as an aid to sensing the earth's magnetic field.

Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism. Today it is mined as iron ore. Small grains of magnetite occur in almost all igneous and metamorphic rocks.

iron | Element, Occurrence, & Compounds |

Iron is also found combined with other elements in hundreds of minerals; of greatest importance as iron ore are hematite (ferric oxide, Fe 2 O 3), magnetite (triiron tetroxide, Fe 3 O 4), limonite (hydrated ferric oxide hydroxide, FeO(OH)nH 2 O), and siderite (ferrous carbonate, FeCO 3). Igneous rocks average about 5 percent iron content.

Metal Profile: Iron Properties and Characteristics

Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BC.
