A non - conducting rod of length L with ...

A non - conducting rod of length L with linear charge density `lambda=lambda_(0)x` where x is the distance from end A is rotating with constant angular speed `omega` about the same end. If the angular velocity of the rod `(omega)` is large, then the magnetic dipole moment of the system is `(omega lambda_(0)L^(4))/(n)`. What is the value of n?
