Question

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

in the above , what is emf induced when current is reduced to zero and then increases again to 1.5 A in reverse direction in 25ms ​

hi dear friend

I will tell you

can you tell me that what are you mean to say
