A rectangular and a circular loop are moving out of the uniform magnetic field region with a constant velocity.In which loop will the induced Emf be more? Is it in the circular loop, since it will have more Area?

In rectangular coil, the induced emf will be constant because in this case the rate of change of area in magnetic field remains constant whereas in circular coil the rate of change of area in magnetic field is not constant and is more .hence induced emf is more.
