A 30-turn coil has a diameter of 14 cm. The coil is placed in a spatially uniform magnetic field of magnitude 0.5 T so that the face of the coil and the magnetic field are perpendicular. Find the magnitude of the voltage induced in the coil if the magnetic field is reduced to zero uniformly in (a) 0.10 s, (b) 1.0 s, and (c) 60 s.
