Question

The motional emf does not depend upon:​

Answer 1

Answer:

Therefore, it depends only on the number of turns and the rate of change of magnetic flux. It may happen that rate of change depends on the area of cross section but this is always not the case. ... A coil is placed in a uniform magnetic field but its area is shrinking at some given rate.
