A current I=1.5A going to a long solenoid of diameter 3.2 centimetre having 220 turns per centimetre. At its centre 130 turn closely coil of diameter 2.1 centimetre 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 25ms. A) What is the magnitude of the EMF induced in the coil while the current in the solenoid is changing? B) Also find the EMF induced in the coil if it was positioned such that its plane contains the axis of the solenoid? C) what is the EMF induced when the current is reduced to zero and then increases again to 1.5 ampere in reverse direction in 25 ms?
