Two identical conducting bars, labeled (a) and (b), are shown in end view. A uniform magnetic field points downward. Bar (a) is moving straight downward (in the same direction as the magnetic field), while bar (b) is moving to the right (perpendicular to the magnetic field). . For which bar is the magnitude of the induced electric field greater? XS 1) Which of the following statements is true? A motional emf exists in the bar for case (a), but not for case (b) A motional emf exists in the bar for case (b), but not for case (a) A motional emf exists in the bar for both cases (a) and (b) A motional emf exists in the bar for neither case (a) nor case (b)
