Hey Guys: If the only thing that passes through the H/B field is a photon, and not be affected. That seems to be very valuable info. Is it because photons have no mass?, or the feild prevents the photons from aquiring mass. I believe that light has mass, when concentrated enough, or maybe I should have said energy. I welcome any enlightenment on this subgect. Machiaventa,Please Register or Log in to view the hidden image!
