A rectangular, a square, a circular and an elliptical loop, all in the (x-y) plane, are moving out of a uniform magnetic field with a constant velocity, \overrightarrow{ {\V}= {\v} \cdot \hat{ {\i}}. The magnetic field is directed along the negative z-axis direction. The induced emf, during the passage of these loops, come out of the field region, will not remain constant for :

Correct Answer is : The circular and the elliptical loops
