A square metallic wire loop of side $0.1\,\,m$ and resistance of $1\,\,{\rm{\Omega }}$ is moved with a constant velocity in a magnetic field of $2\,\,wb/{m^2}$ as shown in figure. The magnetic field is perpendicular to the plane of the loop, loop is connected to a network of resistances. What should be the velocity of loop so as to have steady current of $1\,\,mA$ in loop <BR>.
