Solution to task 462 from Chertov´s for extramural stud

462. In a uniform magnetic field with induction B = 0.5 T, a rod with a length of l = 20 cm rotates with a frequency of n = 10 s-1. The axis of rotation is parallel to the induction lines and passes through one of the ends of the rod perpendicular to its axis. Determine the potential difference U at the ends of the rod.
