Why is it only iron, cobalt, and nickel that is magnetic?

Iron (Fe), cobalt (Co), nickel (Ni), and gadolinium (Gd) are the only four elements that are ferromagnetic in their elemental forms under room temperature. Some elements like terbium (Tb), dysprosium (Dy) and holmium (Ho) are only ferromagnetic under low temperatures.

Why are Iron, Cobalt and Nickel Magnetic? Physics Forums

Apr 18, 2010 Since the dipoles are pointing in random directions, the magnetic field is nearly zero. However, if the material is ferromagnetic, once one introduces a mild external magnetic field, those dipoles line up and you get a strong magnetic field. Other materials have atoms which don't tend to line their magnetic dipoles as much.

Q: What causes iron, nickel, and cobalt to be attracted to

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.

Cobalt is similar to iron and nickel, and — like iron — it is ferromagnetic and can be made very magnetic.
