PhysicsEasysingle choice

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

Options:

Answer:

Solution:

The equivalent current due to the motion of the electron is

$i = e υ$

So, the magnetic moment will be

$M = i \times π r^{2} = π e υ r^{2}$
