According to the wire length l = 60 cm, in a uniform magnetic field with induction B = 1.2 T, and located in a plane perpendicular to the direction of the field, the current I flows from the power source to the voltage U = 7 V. For wire acts the electromagnetic force F, Move it a speed V = 8 m / s. Resistance wire connecting wires R = 0,5 Ohm. Determine the value of the current I0 at a fixed wire, back-EMF induced in the wire, and the current I when it is moved.
