A flаt cоil оf wire hаs аn area оf 0.020 m2 and contains 50 turns. Initially the coil is oriented so that the normal to its surface is parallel to and in the same direction as a constant magnetic field of 0.18 T. The coil is then rotated through an angle of 30° in a time of 0.10 s. What is the average induced emf?
