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 `Vvec` = `v_(0)hati`. The magnetic field is directed along the negative z-axis direction. The induced emf, during the passage of these loops, out of the field region, will not remain constant for

Options

A. the rectangular, the circular and the elliptical loops
B. the circular and the elliptical loops
C. only the elliptical loop
D. any of the four loops.
