Ahorizontal circular wire loop of radius 0.5 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 0.45 t. if in 0.14 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.
