I came across a question where it said a electrons rotates in a circular path with a angular velocity in the presence of a perpendicular varying magnetic field.
It was asked what is the change in the magnetic moment of the electron.
The solution equated the change in magnetic moment to (constant of proportionality)(change in angular momentum)*. I do not understand the concept behind this. How are the both related?
I was viewing the discussion at Why are the magnetic moment and the angular moment related? but it doesn't answer to the question precisely. Please include some examples if possible.
