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 fabrie very strong rareearth magnets.

EARTH''S MAGNETISM & MAGNETIC DIPOLE. Historically,Thales
Mar 29, 2018 · EARTH''S MAGNETISM & MAGNETIC DIPOLE .Historically,Thales of Miletus knew that pieces of lodestone or magnetite (black iron oxide a naturally occurring iron ore) could attract small piece of iron . further, the small pieces of iron could themselves acquire this property.
Magnetite: Mineral information, data and localities.
JacobsiteMagnetite Series. MagnesioferriteMagnetite Series. Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).
Jan 25, 2013 · Lodestones are made of an iron ore called "magnetite" (Fe 3 O 4), the only naturally occurring material that exhibits significant magnetism. By the 12 th century, it was known that lodestones carried two points of maximum attraction, called poles, and that these poles aligned with certain directions on the Earth.
Jun 11, 2013 · Magnetite – Wikipedia, the free encyclopedia. Not to be confused with Magnesite or Maghemite. Magnetite is a mineral, one of the two common naturally occurring iron oxides (chemical formula Magnetite is the most magnetic of all the naturally occurring minerals on Earth.
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.

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe3O4. It is one of the oxides of iron, and is ferrimagnetic naturallyoccurring minerals on Earth. Naturallymagnetized pieces of magnetite, called lodestone. Today it is mined as iron ore. We supply to a wide variety of industries, enquire now for a quotation.
Magnetism was first discovered in a natural rock called magnetite, or lodestone. Its strange property of attracting iron objects was known nearly 3,000 years ago. Later, Chinese explorers discovered that a piece of lodestone, if able to move freely, would always point north. This led to
Magnetite Fe3O4. Magnetite is a mineral and one of the main iron ores. With the chemical formula is Fe3O4, it is one of the oxides of iron.Magnetite is ferrimagnetic, which means it is attracted to a magnet is the most magnetic of all the naturallyoccurring minerals on Earth. Naturallymagnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient
Naturally magnetized magnetite is called lodestone. Normally it is only attracted to hand magnet, but magnetite itself does not attract objects mader of iron. Lodestone is different because it does that too and it readily aligns itself along the magnetic lines of the Earth. This makes lodestone useful in navigation as a natural magnetic compass.

The Magnetic Minerals Amethyst Galleries'' Mineral Gallery
The Magnetic Minerals are few, but the property is important because of this fact. Once a specimen is established as magnetic, identifiion 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.
Magnetic and NonMagnetic Substances The substances which are strongly attracted by magnets are called magnetic substances. For example, iron, cobalt, nickel and their alloys are magnetic substances. The substances which are not attracted by a magnet are called nonmagnetic substances. For example, wood, paper, water, copper, glass, gold, silver, etc., are nonmagnetic substances.
What Are Natural Magnets? 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.
