How does magnetic interactions happen in proximity?

[1832vin]

is it explained? (proximity = between protons and electrons distance)
is it a dispersion field (a more general term for boson field, but for everything, cause' i don't know what is right)
or is it about something else in total?

i tried to find it, but yahoo answers came up...
can someone point me to the right topics?

What does "it" mean? Quantum electrodynamics works, and it can fully describe the electromagnetic interaction.

That does not make sense.
