In this question, we are given a graph of magnetic field versus time taken in which we are given a specific regions like this, then it is moving in constant, then it is decreasing.
00:17
So, this region is named as a and up to this, it is named as b and this region is named as c and here this region is d and this region is e.
00:36
We are asked to find the emf and rank them according to the from greatest to the lowest in the regions given here.
00:46
So, first let us analyze in region a and region a is a horizontal line parallel to t and here also the magnetic field is constant with time.
01:03
Hence, let us take region a and c.
01:06
So, in both the regions as here slope equal to 0 as they are horizontal, as the slope is equal to 0, we can say that there is no change in the flux.
01:25
As there is no change in the magnetic flux value, there will be no emf produced.
01:34
As there is no emf, we can say emf at a and equal to emf at c region equal to 0.
01:43
Then let us analyze in region b.
01:48
So, region b is strictly increasing...
