At first, I want to say that electromagnetism is my weakest physics branch so this question might sound silly. Electromagnetism unified electricity with magnetism and the quanta of electromagnetic force is a photon. Is there any link between magnets and photons? Is there any link between electricity and photons? I mean do photons play any kind of a role in magnetism or electricity? I ask these questions because as far as I know, only electrons are responsible for these things.
