A flexible loop of conducting wire has a radius of 0.12 m and is perpendicular to a uniform magnetic field with a strength of 0.15 T,as in figure (a) below.The loop is grasped at opposite ends and stretched until it closes to an area of (3)(10^-3)(m^2), as in figure (b) below. If it takes 0.20s to close the loop, find the magnitude of the average emf induced in the loop during this time.

A flexible loop of
0.12 m and is perpendicular to a uniform magnetic field
with a strength of 0.15 T,as in figure (a) below.The loop
is grasped at opposite ends and stretched until it closes
to an area of (3)(10^-3)(m^2), as in figure (b) below. If it takes 0.20s to close the loop, find the magnitude of the average emf induced in the loop during this time.
