Most metals are not magnetic but iron is why?

 This is because of the way that the electrons in an atom of iron behave. The electrons in an iron atom tend to have the ability to align themselves and face one toward one direction such that one side of the atom has high negative charge and the other side has a high positive charge. So then that atom will behave like a tiny magnet.

 Now when many of these "tiny magnets"  line up, their combined attraction creates the force known as magnetism.

Most other elements do not have this unique property that iron has and that is why they are not magnetic.  

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

i believe the answer is electric potential.
