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

I want an exact answer for it. You have given that iron, nickel and cobalt possess one or more unpaired electrons and because of that the magnetic fields of these electrons aren't cancelled out by another oppositely oriented electrons. It is absolutely correct. But the metals such as Mn, Cu, Al, Cr also possess unpaired electrons know.

Manganese has more unpaired electrons than Iron so why is ...

The magnetic moments of such magnetic atoms are oriented randomly and their magnetic moments cancel out each other and no permanent magnet. But by applying an external magnetic field the magnetic moments are oriented in the same direction with the applied field so the outcome field from the material is larger than the applied.

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. Atoms of wood do not have unpaired electron spins that can line up with a magnet, …
