Hello all, I have a question relating to charge. I understand that when a positive charge is near a negative charge it creates an attraction. This attraction is explained by the electromagnetic force and by the exchange of electrons. My question is this, how can a new particle such as a photon come out of another? Is a photon simply a carrier of energy and that is why it happens? Also can an electromagnetic attraction ever lose its attraction by removing all its energy via the transfer of photons?
