Jan 24, 2011 at 15:22 comment added Nigel Seel Thanks for the series of clarificatory thoughts you're adding to this answer. "And if a photon is detected in any way, it definitely has to be a virtual photon" because the act of detection is itself the "external leg", is that correct?

Jan 22, 2011 at 14:49 comment added Nigel Seel I think there are elements to an answer to my question here. Could you link your thoughts above to the specific differences between a static magnetic and static electric field? It's not clear to me how virtual photon polarisation could implement the distinction.
