A long solenoid having `200` turns per centimeter carries a current of `1.5 A`. At the center of the solenoid is placed a coil of `100` turns of cross-sectional area `3.14 xx 10^(-4) m^(2)` having its axis parallel to the field produced by the solenoid. When the direction of current in teh solenoid is reversed within `0.05 s`, the induced emf in the coil is
