Answer #1

For a wire of area A placed in a region of magnetic field b, experiences a flux given by

is the angle between the area vector and the magnetic filed.

For a change in flux over a time , emf induced is

We can see that induced emf is directly proportional to the area of the coil and the rate of change of magnetic flux.

So, with the increase in area and rate of magnetic flux, emf induced increases.
