A 20-turn circular coil of radius 8.0 cm and resistance of 1 ohm is placed in a magnetic field directed perpendicular to the plane of the coil. The magnitude of the magnetic field varies in time, according to the expression B = 0.01 t + 0.05t + 0.06 +3., where B is in tesla and t is in seconds. Calculate the induced emf in the coil at t = 8 s
