84. The conductive rod length l = 0,40 m uniformly rotates in a horizontal plane in a uniform magnetic field. Field lines are directed vertically, the magnetic induction B = 10 mT. The axis of rotation is parallel to the lines of force and passes through the end of the rod. At what rotational speed ν at the ends of the rod a potential difference U = 0,20 B?
