5.25 The magnetic moment vectors µs and µl associated with the intrinsic spin angular momentum and orbital angular momentum l, respectively, of an electron, are predicted by quantum theory (and verified experimentally to a high accuracy) to be given by:

µs = –(e/mS,

µl = –(e/2m)l

Which of these relations is in accordance with the result expected classically? Outline the derivation of the classical result.
