A 15.5-cm-diameter loop of wire is initially oriented perpendicular to a 1.2-T magnetic field. The loop is rotated so that its plane is parallel to the field direction in 0.29 s . What is the average induced emf in the loop? Express your answer to two significant figures and include the appropriate units. |
since magnetic field and area of loop is uniform/constant, so
the change in flux is equal to the flux
