(27-40) Suppose a nonconducting rod of length d carries a uniformly distributed charge Q. It is rotated with angular velocity ω about an axis perpendicular to the rod at one end, Fig. 27-48. Show that the magnetic dipole moment of this rod is 1/6Qωd^2. [Hint: Consider the motion of each infinitesimal length of the rod.]
