Solution:
As current in increases with time Magnetic flux changes linked with that coil this change in flux causes current in which also increase with time.
Two coils and are arranged coaxially as shown in figure. The ends of the coil ‘’ are connected to an ammeter A. If the current sent through the coil is directly proportional to the time. If the magnetic field induction produced by the coil is proportional to the current in it, then the induced current through the coil is
As current in increases with time Magnetic flux changes linked with that coil this change in flux causes current in which also increase with time.
