The element Nickel (Ni) is one of the few ferromagnetic metals. Ferromagnetic means they are attracted to magnets and can be magnetized themselves. Most metals arenât magnetic with the exception of iron, nickel, cobalt, gadolinium, neodymium and samarium.
Diamagnetic Metals. The term diamagnetic is a more technically accurate way of describing a material that is not attracted to a magnet. The atoms or molecules of a diamagnetic substance do not have net dipole moments, so they do not act as magnets.A diamagnetic substance is pushed out of a magnetic field, but with most materials the force is so weak you won't be able to observe it in everyday life.
