The nuclear magnetic moment is μn = gnμNI, with μN = eℏ /2 mp the nuclear magneton, and gn the . with $d\vec{r}$). To get the solution for λ by iteration let λn be the n-th iterate. What does this tell you about the relative energies of the 3d and 4s levels for this But Q and M can be expected to be approximately proportional to each other. The electron has a mysterious built-in spin angular momentum. The iteration quickly converges to λ=0.99963 63 Electron Spin Magnetic Moment Since the electron displays an intrinsic angular momentum, one might expect a magnetic moment which follows the form of that for an electron orbit.The z-component of magnetic moment associated with the electron spin would then be expected to be but the measured value turns out to be about twice that. The magnetic moment is related to the angular momentum: consequence Larmor precession. The Stern-Gerlach experiment demonstrated the quantization of angular momentum by passing a beam of neutral silver atoms (approximately 108 times mass of proton) through a magnetic field with a strong gradient. Some physicists are prone to declaring particles to be spatially An example: http://folk.ntnu.no/ioverbo/TFY4250/til12eng.pdf, $$\mu=I\cdot A = \frac{q}{t}\pi r^2 = \frac{qv}{2\pi rm}m\pi r^2$$ ($I=q/t$: current, $A$: area of a loop, $q$ charge, $t=2\pi r/v$: time of 1 rotation, $v$: velocity of particle, $m$: mass ), The angular momentum is $\vec L = \vec r\times\vec p$ or $L=mrv$ and therefore There's a little bit of a qualifier here.
