What is static magnetic field in terms of the relativistic quantum physics? How the photons form the static magnetic field? How they are doing that?

In relativistic quantum physics, a theoretical concept of the photon is formulated as the quantum of the (electro)magnetic field. How is working that concept in the particular case of static...

What is the magnetic field, created by ion of Fe^{+2} (for electron of conductivity), if the ion magnetic moment equals 5.1 Bohr's magneton?

For example, to get answer, could we use classical formula (44.4) from the book Landau,Lifshitz "Theory of field" (see the attached photo) ?It's because, we suppose, the distance between the...
