If carriers of electromagnetic force are photons, it also means that magnetic fields surrounding magnets are also “composed” of photons. I must confess that I am confused by this, especially as magnetic fields and its effects on matter do not show any similarity with light, which is a form of electromagnetic radiation, itself also made of photons. If both electromagnetic radiation and magnetic field are carried by photons, then why light doesn’t cause a piece of iron to move around as magnetic field does. If it is made of photons, why photons of magnetic field don’t excite electrons of atoms that they “hit” to higher energy level as photons of electromagnetic radiation do? Do photons comprising a magnetic field have a particular wavelength/frequency as photons of electromagnetic radiation do? Why are these “same” things, so strikingly different in their manifestations?
