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:NEET 2007

Options:

Answer:

Solution:

Magnetic moment $μ = I A$ Since $T = \frac{2 π R}{v}$ also $I = \frac{q}{T} = \frac{q v}{2 π R}$ $∴ μ = (\frac{q v}{2 π R}) (π R^{2}) = \frac{q v R}{2}$
