Charge and magnetic moment of an electron.

Featured Replies

How do they relate? If velocity increases magnetic moment, is charge affected?(Lenz's law).

Edited by Butch

The charge of an electron is constant AFAIK. If I am wrong, someone will let us know.

The magnetic moment is given by g(-e/2m)L where g is the g-factor (related to the gyromagnetic ratio), and L is the angular momentum. L can be orbital and/or spin angular momentum, so an electron has an inherent magnetic moment owing to its spin.

I apologise for not making my inquiry clear, however it has festered and come into better focus...

Consider the following:

Electron A has velocity that produces magnetic moment n1, electron B has velocity that produces magnetic moment n2.

Would the force between A and B be greater than that stated in Coulomb's law?

If not why?

It doesn't, does it?

Hmm, it was my understanding that it did, perhaps I should reread?

Okay, if it is orbital L would that not affect the force between particles?

Velocity does not produce the magnetic moment. It will produce a magnetic field, as would any moving charge.

Yes, and it would be responsible for a small shift in the energy levels of the atom.

Thank you.
