No, silver is not magnetic. It is considered diamagnetic, which means it exhibits weak repulsion in the presence of a magnetic field. 1 Unlike ferromagnetic materials like iron or nickel, silver does not possess unpaired electrons that can align and create a strong magnetic moment. 2. Well, this was just a simple answer.
