Questions
A charged particle (charge q) is moving in a circle of radius R with uniform speed v. The associated magnetic moment is given by
detailed solution
Correct option is A
As revolving charge is equivalent to a current loop, so electric current corresponds to the revolution of electron is I=q f=q × ω2πBut ω=vR, where R is radius of circle and v is uniform speed of charged particle. Therefore, I=qv2πRNow, magnetic moment associated with charged particle is given byor μ=qv2πR × πR2 = 12 qvRTalk to our academic expert!
