Here's an element factoid for you: Not all iron is magnetic. The a allotrope is magnetic, yet when the temperature increases so that the a form changes to the b form, the magnetism disappears even though the lattice doesn't change.

On a related note, iron isn't the only metal to display magnetism. Under certain condition, manganese is ferromagnetic.
