Two coils C1 and C2 are arranged coaxially as shown in figure. The ends of the coil ‘C2’ are connected to an ammeter A. If the current sent through the coil C1 is directly proportional to the time. If the magnetic field induction produced by the coil C1 is proportional to the current in it, then the induced current through the coil C2 is

Two coils $C_{1}$ and $C_{2}$ are arranged coaxially as shown in figure. The ends of the coil ‘ $C_{2}$ ’ are connected to an ammeter A. If the current sent through the coil $C_{1}$ is directly proportional to the time. If the magnetic field induction produced by the coil $C_{1}$ is proportional to the current in it, then the induced current through the coil $C_{2}$ is

A
zero
B
increasing with time
C
constant
D
decreasing with time

Solution:

As current in $C_{1}$ increases with time Magnetic flux changes linked with that coil this change in flux causes current in $C_{2}$ which also increase with time.
