Question:

Options:

a

b

c

d

Correct Answer:

a

Explanation:

Since the current is increasing, so inward magnetic flux linked with the ring also increasing . Hence induced current in the ring is anticlockwise, so end x will be positive.

$\text{Flux} \phi = BA= (B_0 + \alpha t)A$

$\xi = A \frac{dB}{dt} = A\alpha$
