Do the electron pair in an orbital, have a net orbital magnetic moment?

It has been made clear to me that 2 electrons in an orbital have opposite spins, and hence their spin magnetic moment nullify each other.But does the same happen...

How does Stern-Gerlach experiment lead to conclusion of electron's spin?

As far as I understood in the Stern-Gerlach experiment, silver atoms while passing through an external inhomogeneous magnetic field they split into two groups. My question is how does that...

Magnetic monopole, vector-potential and differential forms

When written in the language of exterior algebra, Maxwell-Thomson equation writes as $dB=0$ where $d$ is the exterior derivative and $B$ is the magnetic flux 2-form. From...

Magnetic moments of nucleons

I was comparing my notes of the nuclear physics class (undergraduate level) on magnetic moments of nucleons with the Krane's explanation. In my notes I wrote that there are...

What is the role of sound in string theory?

Densely packed strings (perhaps in a fuzzball scenario) should impact one another frequently and transmit sound. If they're densely packed enough, the sounds produced might be affected by the fact...

Are multiple images an exclusive propertiy of gravitational lenses?

Strong gravitational lensing produces multiple images if the object lens and observer are in a specific alignment. This is due to there being multiple stationary points in the time arrival...

Translation of coordinates to generalised coordinates

The translation form $r_i$ to $q_j$ language start forms the transformation equation: $r_i=r_i (q_1,q_2,…,q_n,t)$ (assuming $n$ independent coordinates) Since...
