A horizontal circular wire loop of radius 0.4 m lies in a plane perpendicular to a uniform magnetic field that is pointing down from above into the plane of the loop, and has a constant magnitude of 0.41 T. If in 0.04 s the wire is reshaped from a circle into a square, but remains in the same plane, what is the magnitude of the average induced emf in the wire during this time? [Hint: what remains constant during the change is the total length of the wire that formed the initial loop.] Answer in units of V

I got 1.131 V
