WebIn physical cosmology, the photon epoch was the period in the evolution of the early universe in which photons dominated the energy of the universe. The photon epoch … WebThe mass of an atom = 1.6605402×10^-24 gm and mass of a photon = 1.659×10^-54 gm. Therefore, one atom is 1.00055469×10^30 times larger than a photon, thus we can say atom made by 1.00055469×10^30 photons. Similarly, all matter made by photons. Again, one photon contain 10^107 unknown particles.

The magnetic field isn't made of photons. Photons are made of magnetic (rather, electromagnetic) fields. To be specific, photons are ripples in the electromagnetic field.
