A horizontal square wire loop of side d lies in a plane perpendicular to a uniform magnetic field B pointing from above into the plane of the loop. The magnitude of magnetic eld ~ B is: B = 0.80 T. If in ∆t = 4.0 ms the wire is reshaped from a square to a rectangle of dimensions: L = 10.0 cm; W = 6.0 cm, but remains in the same plane. a - What is the side d of the square? b - What is the magnitude of the average induced emf, in the wire during this time?
