A rod of length \( \ell \) having uniformly distributed charge \( Q \) is rotated about one end with constant frequency ' \( f \) '. Its magnetic moment.
(A) \( \pi \mathrm{fQ} \ell^{2} \)
(B) \( \frac{\pi \mathrm{fQ} \ell^{2}}{3} \)
(C) \( \frac{2 \pi \mathrm{fQ} \ell^{2}}{3} \)
(D) \( 2 \pi \mathrm{fQ} \ell^{2} \)
