A current I = 1.5 A is flowing through a long solenoid of diameter 3.2 cm, having 220 turns per
cm. At its centre, a 130 turn closely packed coil of diameter 2.1 cm is placed such that the coil
is coaxial with the long solenoid. The current in the solenoid is reduced to zero at a steady rate
in 25 ms. WWhat is the magnitude of emf induced in the coil while the current in the solenoid is
changing?
