A charge particle having charge q is moving in a circle of radius R with a uniform speed v. The associated magnetic moment μ is
Answer & explanation
Correct answer: option 1
magnetic Moment $ \mu = IA $
$ I = \frac{q}{T} = \frac{qV}{2\pi R}$
$ \mu = IA = \frac{qV}{2\pi R}\times \pi R^2 = \frac{qVR}{2}$
