A flat coil of wire has an area of 0.022 m and consists of 150 turns. At t=0 s, the coil is oriented so the normal to its surface has the same direction (θ=0) as a constant magnetic field of magnitude 0.45 T. The coil is then rotated through an angle of θ=40.0° in a time of 0.33 s. Determine the average induced emf. +0.94 V -0.26 V -0.54 V +1.1 V
