A charge of q = 240 nC is uniformly distributed over a thin rod of length l = 20 cm. The rod is rotated with a constant angular velocity ω = 10 rad/s relative to an axis perpendicular to the rod and passing through its middle. Determine: 1) magnetic moment pm caused by the rotation of the charged rod; 2) the ratio of the magnetic moment to the angular momentum (rm/L), if the rod has a mass m = 12 g.
