May 29, 2010 · 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.
