Hello! I want to make sure I understand (mainly qualitatively) what happens to an atom in a magnetic field. Assume we have an atom with an even number of protons and electrons. This means that all proton (electrons) are paired up, except for one of them (I am not totally sure if this pairing is always the case, especially for mid-shell nuclei, but let's assume this for now). If the electron has a total angular momentum of ##j_e## and proton of ##j_p##, they have a magnetic moment of ##\mu_e = g_e\mu_B j_e## and ##\mu_p=g_p\mu_Nj_p##, with ##g_e## and ##g_p## the effective g-factor of the electron and proton. Ignoring higher order effects, in a magnetic field these 2 magnetic moment would interact with the magnetic field and assuming we have very low temperature, they would align (or anti align) with the magnetic field. Is this it, or does something else happens in terms of the behavior of the 2 magnetic moments? Can I treat them separately i.e. if for example I need polarized nuclei, would the electron magnetic interaction have a major effect?
