Where Can Iron Be Found? | Reference.com

Iron can be found in the Earth's core, in the Earth's crust, in hemoglobin, in steel and in magnets. It is rare to find iron in its elemental form on Earth, but it has been found in igneous rocks in Russia. Iron is a shiny gray metal. When it oxidizes, the resulting compound is known as iron oxide or rust. Iron rusts in damp air but not in dry air.

Paramagnetism - Wikipedia

Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field. In contrast with this behavior, diamagnetic materials are repelled by magnetic fields and form induced magnetic fields in the direction opposite to that of the applied magnetic field.

Any magnet, including a permanent magnet or the Earth, will attract any ferromagnetic material, not just iron. Some other examples include cobalt and nickel. Magnets magnetically attract paramagnetic materials more weakly and repel diamagnetic materials.

How to Extract Iron From Sand | Sciencing

Apr 24, 2017· You probably won't remove all the iron in the first pouring. The iron you extract will still be mixed with impurities. In a commercial operation, the first extraction would be ground and passed through another, more sensitive extractor with weaker magnets that don't attract semi-magnetic …

Meteorite Museum - University of New Mexico

Most meteorites contain some iron-nickel metal and attract a magnet easily. You can use an ordinary refrigerator magnet to test this property. A magnet will stick to the meteorite if it contains much metal. Some meteorites, such as stony meteorites, contain only a small amount of metal, but will attract a magnet hanging on a string.

KEY CONCEPT Magnetism is a force that acts at a distance.

However magnets cannot exert a force on an object that is too far away. A is the region around a magnet in which the magnet exerts force. If a piece of iron is within the magnetic field of a magnet, it will be pulled toward the magnet. Many small pieces of iron, called iron filings, are used to show the magnetic field around a magnet.

1 Magnets and Magnetism - Rainbow Resource Center, Inc.

Section 1 Magnets and Magnetism 513 Losing Alignment The domains of a magnet may not always stay lined up. When domains move, the magnet is demagnetized, or loses its mag-netic properties. Dropping a magnet or hitting it too hard can move the domains. Putting the magnet in a strong magnetic field that is opposite to its own can also move domains.

Magnetic Methods | Environmental Geophysics | US EPA

Many rocks and minerals are weakly magnetic or are magnetized by induction in the Earth's field, and cause spatial perturbations or "anomalies" in the Earth's main field. Man-made objects containing iron or steel are often highly magnetized and locally can cause large anomalies up to several thousands of nT.

Magnet - Wikipedia

Magnets can be used in scrap and salvage operations to separate magnetic metals (iron, cobalt, and nickel) from non-magnetic metals (aluminum, non-ferrous alloys, etc.). The same idea can be used in the so-called "magnet test", in which an auto body is inspected with a magnet to detect areas repaired using fiberglass or plastic putty.
