The induced e.m.f. will remain constant only in the case of rectangular and square loops. In case of the circular and elliptical loops, the rate of change of area of the loops during their passage out of the field is not constant, hence induced e.m.f. will not remain constant for them.

1. The induced e.m.f. will remain constant only in the case of rectangular and square loops.
2. The induced e.m.f. will remain constant only in the case of circular loops.
3. The induced e.m.f. will remain constant only in the case of elliptical loops.
4. The induced e.m.f. will remain constant only in the case of triangular loops.

Correct answer: The induced e.m.f. will remain constant only in the case of rectangular and square loops.

Solution

The induced e.m.f. depends on the rate of change of magnetic flux, which is proportional to the rate of change of the area exposed to the magnetic field. For rectangular and square loops, this rate remains constant during motion, unlike circular or elliptical loops.
