A long solenoid having 450 turns per m carries a current of 1.6 A. At the centre of the solenoid a coil of 180 turns with cross sectional area `3.5 cm^(2)` is placed having its axis parallel to the field produced by the solenoid. What will be the amount of induced emf when the direction of current in the solenoid is reversed within 0.03 s?

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
