You plan to move a rectangular loop of wire (consider only the loop at left) into a region of uniform magnetic field B at a given speed so as to induce an emf in the loop. The plane of the loop must remain perpendicular to the magnetic field lines as shown. In which orientation should you hold the loop while you move it into the region of B to generate the largest emf?
