Current Loop as a Magnetic Dipole

In a hydrogen atom, an electron of charge ee revolves in a orbit of radius rr with speed vv. Then, magnetic moment associated with electron is

Show answer and solution

Answer: (a)

  1. I=ev2πrI = \frac{ev}{2\pi r}
  2. μ=Iπr2=evr2\mu = I\pi r^2 = \frac{evr}{2}, so the answer is (a).
