Question
The graph 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
- b > (d = e) < (a = c)
- b > (d = e) > (a = c)
- b < d < e < c < a
- b > (a = c) > (d = e)
The correct answer is: b > (d = e) > (a = c)
Induced emf 
i.e. 
(= slope of B – t graph)
In the given graph slope of AB > slope of CD, slope in the ‘a’ region = slope in the ‘c’ region = 0, slope in the ‘d’ region = slope in the ‘e’ region 
. That’s why
