Answer & explanation
Correct answer: option 1
$\text{Induced EMF } \xi = \frac{d\phi}{dt} = 8t -4 $
$\text{ at t = 1/2 second } \xi = 0$
$\text{Induced Current }I = \frac{\xi}{R} = 0$
Correct answer: option 1
$\text{Induced EMF } \xi = \frac{d\phi}{dt} = 8t -4 $
$\text{ at t = 1/2 second } \xi = 0$
$\text{Induced Current }I = \frac{\xi}{R} = 0$
