A long solenoid with 2,119 turns/m has a cross-sectional area of 0.35 m² and a current given by the equation i(t) = B + Ct², where t is in seconds, B = 4.93 A, and C = 2.48 A/s². A flat circular coil with 338 turns and cross-sectional area of 0.21 m² lies inside and is coaxial with the solenoid. What is the magnitude of the emf induced in the coil at t = 7.84 s?
