A metal frame in the shape of the letter “P” is located vertically in a uniform magnetic field, the induction vector B is directed perpendicular to the plane of the frame (Fig. 10.19). The metal rod AB begins to move vertically downwards from a state of rest. The rod is in electrical contact with the vertical sides of the frame, but moves along them without friction. Determine the speed v of the movement of the rod t seconds after the start of movement. The mass of the rod is m, the electrical resistance of the rod is R, the distance between the points of contact of the rod with the frame is I. The electrical resistance of the frame and its inductance are negligible. Neglect self-induction.
