A charged particle (charge q) is moving in a circle of radius R with uniform speed v. The associated magnetic moment µ is given by:
A
B
qvR 2
C
D
qvR
Text Solution
Verified by ExpertsThe correct answer is:
A
As revolving charge is equivalent to a current, so
But 
where 
is radius of circle and 
is uniform speed of charged particle.
Therefore, 
Now, magnetic moment associated with charged particle is given by
or
