A metallic square wire loop of side 10 cm and resistance 1Ω is moved with a constant velocity v0 in a uniform magnetic field of induction B = 2 T as shown in the figure. The magnetic field perpendicular to the plane of the loop. The loop is connected to a network of resistors each of value 3 ohm. The resistance of the lead wires OS and PQ are negligible. What should be the speed of the loop so as to have a steady current of 1 mA in it? Give the direction of current in the loop.
