why is iron magnetic

Why is iron magnetic? - Quora

Magnetism is caused by the movement of electrons. In iron atoms, it just so happens that the electron configuration leaves two unpaired electrons. When iron atoms are lined up in a crystal, it also just so happens that those same unpaired electron...

Iron and Magnets | sciphile.org

Most magnetic atoms (i.e. atoms that do not have filled electron shells) prefer to align so that nearest neighbors have magnetic fields pointing in opposite directions, with the south pole of one atom next to the north pole of the neighbor, and the north pole next to the south pole of the neighbor.

Why is iron magnetic? | Yahoo Answers

2010-03-11· 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 …

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

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.

Iron - University of Denver

Silicon iron as a magnetic material was developed by Sir Robert Hadfield in England, and was introduced to the United States by the Allegheny Steel Company in 1903. As silicon is added, the iron becomes a better and better magnetic material as its electrical resistivity increases, but it also becomes brittle and difficult to work. At 4.25% silicon, its resistivity is about 60 μΩ-cm, more ...

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

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.

Why are Iron, Cobalt and Nickel Magnetic? | Physics Forums

2010-04-18· The atoms in ferromagnetic materials like to align their magnetic dipoles with the external field. Think for example 10 atoms that have randomly distributed magnetic dipoles. Since the dipoles are pointing in random directions, the magnetic field is nearly zero. However, if the material is
