The magnetic moment of a free atom is due to the orbital angular momentum and spin of its electrons and nucleus.
42.
In ferromagnets, the movement creating the magnetic field is the electron spin ( and to a lesser extent electron orbital angular momentum ).
43.
For an electron in an orbital with a magnetic quantum number m l, the " z "-component of the orbital angular momentum is
44.
These were identified as, respectively, the electron " shell " number, the " orbital " number, and the " orbital angular momentum " number.
45.
Full shells and subshells do not contribute to the quantum numbers for total, the total spin angular momentum and for, the total orbital angular momentum.
46.
In this ground state the atom is assumed to have no net orbital angular momentum but only one unpaired electron to give it a spin of half.
47.
Since angular momentum corresponds to rotational motion, the magnetic moment can be related to the orbital angular momentum of the charge carriers in the constituting the current.
48.
There are much hype around Orbital Angular Momentum ( OAM ) but I do not think it will make any difference for this limit, is this correct?
49.
In any case, the intrinsic " spin " addition to the orbital angular momentum of an object can be expressed in terms of the Pauli Lubanski pseudovector.
50.
Electron orbital angular momentum results from the motion of the electron about some fixed external point that we shall take to be the location of the nucleus.
