I read on some physics website somewhere (I forgot which one) that a magnetic field around a bar magnet exists because there is a tiny probability that some electrons exist outside the bar magnet and when they do they emit virtual photons that can interact with other things to create the magnetic force. Is there any truth in this? If not, can you tell me a quantum explantion of magnetism, or point me to a good webpage, Thanks.
