Faraday's law of induction states that a changing magnetic flux through a loop induces an emf (voltage) in the loop: --NA4/. Since the area of the loop is the only quantity that is changing, we can write the change in flux as A--, - BAA. Ignore the minus sign in Faraday's law because we're asked for the magnitude of AA/M. A rectangular loop of wire with sides 0.157 and 0.517 m lies in a plane perpendicular to a constant magnetic field (see part a of the drawing). The magnetic field has a magnitude of 0.881 T and is directed parallel to the normal of the loop's surface. In a time of 0.272s. one-half of the loop is then folded back onto the other half, as indicated in part b of the drawing. Determine the magnitude of the average emf induced in the loop. 海鮮 (a) (お) Number ! Units V x × x
