Answer:
The average induced emf in the rectangular loop is 0.41V
Step-by-step explanation:
We can resolve this problem through the expression for induced emf in the loop.
This expression is,

Where
is the electro magnetic field
B = Magnetic field
A= Area
dt = change in time.
We have all of this values, because the dimension of the object are enough to calculate the Area .

The average induced emf in the rectangular loop is 0.41V
It is because there is a loop between state 1 and state 2. The given data corresponds from B1 to B2. The total change would be measured by (B2-B1), but B2 is zero. So you get (-B1)
