Silver is not attracted by a magnet. Some of the metals that are magnetic include iron, cobalt, nickel and some alloys of rare-earth metals.
How some metals show magnetic behaviour?
All substances show some kind of magnetic behaviour. After all, they are made up of charged particles: electrons and protons. It is the way in which electron clouds arrange themselves in atoms and how groups of these atoms behave that determines the magnetic properties of the material. The atom (or group of atoms) in effect becomes a magnetic dipole or a minibar magnet that can align according to the magnetic field applied. The net effect of all these dipoles determines the magnetic properties of the Magnetic Materials.
