## Main Question or Discussion Point

Could somebody take a stab at explaining how can quantum fluctuations give neutral elementary particles a magnetic moment?

(in the usual explanation given by QFT textbooks, I think there are people around here denying the existence of quantum fluctuations, insert the more neutral expression "quantum corrections" if it suits you but I'm interested in the physical mechanism)
