An electron in an atom has an orbital angular momentum with ml = 0. What is the component morb,z? (J*s) What is the component ?orb,z? (J/T) If an atom is in an external magnetic field B of magnitude 45 mT and directed along the z-axis, what is the potential energy associated with the orientation of the electron's orbital magnetic dipole moment? (J) What is the potential energy associated with the electron's spin magnetic dipole moment? (J) An electron in an atom has an orbital angular momentum with ml = -5. What is the component morb,z?
