Solution to task 428 from Chertov´s for extramural stud

428. A solid cylinder with a radius of R = 4 cm and a height of h = 15 cm carries a charge uniformly distributed over the volume (ρ = 0.1 µC / m3). The cylinder rotates with a frequency of n = 10 s-1 about an axis that coincides with its geometric axis. Find the magnetic moment pm of the cylinder due to its rotation.
