A square metal 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
weber/m2 as shown in the figure. The magnetic field lines are perpendicular to the plane of the loop (directed into the paper). The loop in connected to a network of resistors each of value
3Ω. The resistances 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 the loop?
