Charge and magnetic moment of an electron.

[Butch]

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

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.

It doesn't, does it?

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?

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.
