Question:

In a simple model, the electron in a hydrogen atom orbits the proton at a radius of 53 pm and at a constant speed of 2.2 × 106 m/s. The orbital motion of the electron gives it an orbital magnetic dipole moment.
(a) What is the current I in this current loop?
(b) What is the orbital dipole moment IA?
(c) Compare the orbital dipole moment with the intrinsic magnetic dipole moment of the electron (9.3 × 10−24 A ∙ m2).
