Question

A very long solenoid of radius R is carrying current I(t) = kteᵃᵗ (k > 0), as a function of time (t ≥ 0). counter clockwise current is taken to be positive. A circular conducting coil of radius 2R is placed in the equatorial plane of the solenoid and concentric with the solenoid. The current induced in the outer coil is correctly depicted, as a function of time, by:-

Answer 1

Answer:

B. is the correct answers

when current increase in solenoid then the coil will resist the change and a current induced opposite direction to the solenoid.

but after some current will become constant in the solenoid and rate of change of change will be zero that time so induced current will also become zero.

Explanation:

hope the answer will help you
