A closed loop of cross-sectional area 10^−2 m^2 which has inductance L = 10 mH and negligible resistance is placed ti time- varying magnetic field. Figure shows the variation of B with time for the intervel 4s. The field is perpendicular to the plane of the loop (given at t = 0, B=0, I = 0). The value of the maximum current induced in the loop is
