Question

As the electron revolves in the second Bohr orbit in the hydrogen atom, the corresponding current is (about) 1.3 × 10^-4 A. If the area of the orbit is (about) 1.4 × 10^-19 m² , what is the (approximate) equivalent magnetic moment?

Answer 1

M = IA = (1.3 × 10^-4)(1.4 × 10^-19)

= 1.82 × 10^-23 A∙m² is the (approximate) equivalent magnetic moment.
