Banded iron formation Wikipedia
Banded iron formation. A typical banded iron formation consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe 3 O 4) or hematite (Fe 2 O 3 ), alternating with bands of iron-poor shales and cherts, often red in color, of similar thickness,
Iron Simple English Wikipedia, the free encyclopedia
Iron is a chemical element and a metal.It is the second most common metal on Earth, and the most widely-used metal.It makes up much of the Earth's core, and is the fourth most common element in the Earth's crust.. The metal is used a lot because it is strong and cheap. Iron is the main ingredient used to make steel.Raw iron is magnetic (attracted to magnets), and its compound magnetite is

Magnetic nanoparticles to cure cancer Medical News Today
Nanoparticles with an iron core specifically target tumors and on exposure to a magnetic field, heat up to the extent that they cook cancer cells while healthy ones are unharmed.
The Four Types of Steel Metal Supermarkets
High Carbon Steel Commonly known as "carbon tool steel" it typically has a carbon range between 0.61% and 1.50%. High carbon steel is very difficult to cut, bend and weld. Once heat treated it becomes extremely hard and brittle. This article is the first of a four-part series on the different types of steel.

What is the only rock that sticks to a magnet Answers.com
Magnetite also called Magnetic Iron Ore or Lodestone. This is not quite correct. There is a group of materials called loosely magnetic fluids (strictly, magnetorheological fluids, of which there
How magnet is made material, manufacture, making
The Earth itself is a huge magnet. Some magnets, known as permanent magnets, exert a force on objects without any outside influence. The iron ore magnetite, also known as lodestone, is a natural permanent magnet. Other permanent magnets can be made by
Find a Meteorite Center for Meteorite Studies ASU
Desert varnish is made up of organic material, manganese and iron oxides, and clay minerals and forms a shiny, black coating on the surface of rocks in dry environments. Because this coating can form on a number of different rock types, some desert-varnished rocks can be magnetic, making it easier to confuse them with meteorites.
USGS Geology and Geophysics
Black Sand. The dark minerals in beach sand at right, from Fort Funston, (Golden Gate National Recreation Area, California) are primarily magnetite and amphiboles, which are non-magnetic black minerals. Both of these mineral types tend to fracture into very small grains that collect on the surface of the sand, by virtue of being smaller and,

Q A What are ferrous materials? Department of Physics
The word ferrous usually refers to materials that have a lot of iron in them. It's common for these materials to be strongly magnetic, but not all of them are. Different types of iron and steel are more or less magnetic. High-chromium stainless steel is nearly non-magnetic, while pure iron tends
Magnetic Anisotropy Institute for Rock Magnetism
Magnetic Anisotropy. The theory of ferro- and ferrimagnetism is based on electronic exchange forces. These forces are so strong that these material are spontaneously magnetized, even in the absence of an applied field. Yet, in the laboratory we need to apply magnetic fields to saturate a ferro-

Iron Ores Article about Iron Ores by The Free Dictionary
Iron Ores natural mineral formations that contain iron in amounts and compounds such that the industrial extraction of the metal is feasible. Iron ores vary in their mineral composition, iron content, useful and harmful impurities, conditions of formation, and industrial properties. The most important iron minerals are magnetite, magnesioferrite
Soft Magnetic Materials
Soft Magnetic Materials. Soft magnetic materials are those materials that are easily magnetised and demagnetised. They typically have intrinsic coercivity less than 1000 Am-1.They are used primarily to enhance and/or channel the flux produced by an electric current.
Is Hematite Magnetic? Hunker
Hematite is the mineral form of iron oxide. Much hematite is at least weakly magnetic, although not all. Many of the minerals and rocks sold as magnetic hematite are in fact synthetic. Hematite is a popular stone in jewelry. Strictly speaking, hematite is the name for a specific mineral. Natural hematite is a mineral form of iron oxide.
