A 33 turn circular coil of radius3.00 cm and resistance 1.00 Ω isplaced in a magnetic field directed perpendicular to the plane ofthe coil. The magnitude of the magnetic field varies in timeaccording to the expression B = 0.0100t +0.0400t2, where t is in seconds andB is in teslas. Calculate the magnitude of the induced emf in the coil at t = 4.20 s.
