Question

An electron of charge e is moving in a circular orbit of radius r around a nucleus, at a frequency υ . The magnetic moment associated with the orbital motion of the electron is, 2 π υ e r 2, π υ r 2 2, π e υ r 2, π υ r 2 4

MARKS App · Accepted Answer

The equivalent current due to the motion of the electron is i = e υ So, the magnetic moment will be M = i × π r 2 = π e υ r 2
