An insulating thin rod of length \(\ \ell \) has a \(\ x \) linear charge density \(\ \lambda(x)=\rho_0 \quad \frac{x}{\ell} \) on it. The rod is rotated about an axis passing through the origin \(\ (x=0) \) and perpendicular to the rod. If the rod makes \(\ \mathrm{n} \) rotations per second, then the time averaged magnetic moment of the rod is :  ๐Ÿ“ฒPW App Link - https://bit.ly/YTAI_PWAP ๐ŸŒPW Website - https://www.pw.live
