MCQ

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, $\vec V = v\hat i$. 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

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

✓

Answer

Correct option: A.

the circular and the elliptical loops

a
Once a rectangular loop or a square loop is being drawn out of the field, the rate of cutting the lines of field will be a constant for a square and rectangle, but not for circular or elliptical areas.
