Question

The graphs gives the magnitude B(t) of a uniform magnetic field, that exists throughout a conducting loop, perpendicular to the plane of the loop. Rank the five regions of the graph, according to the magnitude of the emf induced in the loop, greatest first.

Answer 1

$|emf|$

$\left|L\frac{di}{dt}\right|$
Greater slope $\Rightarrow$ greater emf
so slopes are,
$b>(d=e)>(c=a)$
