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 𝑣⃗ = v𝚤̂.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
- any of the four loops
- the circular and elliptical loops
- the rectangular, circular and elliptical loops
- only the elliptical loops
