magnetic field is made of photons?!?!?

That's very nice, Interested Learner. A question -
the electric field from a point charge extends
to infinity in the absence of other charges. How is the electric field in a photon confined to a smaller region ?
Because a photon does not have charge. Also, even in the presence of other charges the electric fields still extend to infinity.
