A square loop of side 12 cm with its sides parallel to X and Y axes is moved with a velocity of `8cms^-1` in the positive x- direction in an enviornment containing a magnetic field in the positive z- direction. The field is neither uniform in space nor constant in time. it has a gradient of `10^-3Tcm^-1` along the negative x-direction (that is it increases by `10^-3 T cm^-1` as one moves in the negative x-direction) and it is decreasing in time at the rate of `10^-3T s^-1`. Determine the direction and magnitude of the induced current in the loop if its resistance is `4.50 m Omega`.
