What Causes Things to Get Magnetized? | Sciencing

Mar 13, 2018· Ferromagnetism is a phenomenon that occurs in some metals, most notably iron, cobalt and nickel, that causes the metal to become magnetic. The atoms in these metals have an unpaired electron, and when the metal is exposed to a sufficiently strong magnetic field, these electrons' spins line up parallel to each other.

Magnet - Wikipedia

A magnet is a material or object that produces a magnetic field.This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field.

Ferromagnetism - HyperPhysics Concepts

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.

Why Is Iron Magnetic and Wood Not? | Reference.com

Why Is Iron Magnetic and Wood Not? Each atom of iron has an unpaired electron whose spin can be lined up to that of the unpaired electron from a neighboring iron atom. The spinning of the charged electron creates a magnetic moment, which in turn can align with an external magnet, thus making iron magnetic. Atoms of wood do not have unpaired ...

Is Iron Magnetic? | Reference.com

Iron is magnetic except when heated to the Curie point. The Curie point, which is sometimes called the Curie Temperature, is the temperature at which some magnetic materials undergo a major change in their structure. The Curie point for iron is 1,418 degrees Fahrenheit or 770 degrees Celsius.

Why is iron magnetic? | Yahoo Answers

Mar 11, 2010· Best Answer: Iron, cobalt and nickel are the main ferromagnetic materials. All materials are diamagnetic (weakly repelled), paramagnetic (weakly attracted) or ferromagnetic (very strongly attracted.) Iron is ferromagnetic because, while the atoms do not have their electron spins lined up at room temperature, it is easy for an applied external magnetic field to torque the atoms around until ...

What are the properties of cast iron? Is it magnetic? - Quora

Oct 02, 2017· The most common type of cast iron is grey cast iron although other types do exist with somewhat different properties.. Cast iron contains a lot of carbon compared to steel, around 3–5% this is more than can be absorbed into the structure of the iron as a proper alloy and so all cast iron contains particles of graphite withing its structure.

May 29, 2010· They almost completely cancel each other out. However, sometimes (in iron, nickel, and cobalt for example) you’ll have one or more un-paired electrons. The magnetic fields of these electrons aren’t canceled out by another, oppositely-oriented, electron. As such they lend an overall magnetic field to the atom they inhabit.

Electrons and Why Magnets Stick | HowStuffWorks

Iron, for example, has four unpaired electrons with the same spin. Because they have no opposing fields to cancel their effects, these electrons have an orbital magnetic moment. The magnetic moment is a vector-- it has a magnitude and a direction. It's related to both the magnetic field strength and the torque that the field exerts.
