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 rareearth magnets.

Most people know that iron is attracted to magnets, while other metals like gold and silver are not. Yet few people can explain exactly why iron has this magical relationship with .

A piece of iron ordinarily will be attracted to a magnet, but when you heat the iron to a high enough temperature (called the Curie point), it loses its ability to be magnetized. Heat energy scrambles the iron atoms so they can't line up and create a magnetic field—this Snack is a simple demonstration of this effect.

Before a piece of iron first enters the magnetic field of a magnet. the polarisation of the iron's atoms is random. As it is exposed to the magnetic field, the atoms of the iron begin to align their electrons with the flow of the magnetic field, which makes the iron magnetised as well.

Electrons in orbit around an atomic nucleus usually come in pairs, having opposite spin and hence having magnetic poles pointing in opposite.

When you remove the iron from the strong external magnetic field some of the tiny magnets will rearrange themselves again but in general the piece of iron will stay magnetized (due to the domains that changed their internal orientations and stays in the new configuration).

Iron in your body is not ferromagnetic. The strong attraction of iron to a magnet is due to ferromagnetism. This is magnetism in the colloquial sense. Ferromagnetism occurs in some materials which have molecules with a permanent magnetic dipole moment.
