The spin orbit coupling can be explained through two different frames one is the electron frame and the other, the lab frame. In the electron frame magnetic field produced by proton current current exerts torque on electron magnetic dipole and in lab frame torque is exerted on electric dipole of moving electron magnetic dipole by electric field of proton.But can't it also be seen as magnetic field by moving electron interacting with its intrinsic magnetic dipole? I saw this once in PBS spacetime video but I haven't seen it in any quantum physics book e.g Griffiths. Why is that the case? Is it somehow equivalent to the lab frame?
