I am given the radius of the roll, strength of the field, and a velocity at which the wire is unrolled.

How do i calculate the magnitude of the EMF induced in the wire??

In your example your, magnetic_flux is const. and equal to BS=pi (r)^2 B. And only N changes in time. Try to think about dependence between N and time
