A 30-turns coil has a diameter of 14 cm. The coil is placed in spatially uniform magnetic field of the magnitude 0.5 T so that the face of the coil and the magnitude field are perpendicular. Find the magnitude of voltage induced in the coil if the magnetic field is reduced to zero uniformly : a)- 0.10 sec b)- 1 sec
