A 93.3 turns circular coil with radius 6.57 cm and resistance 2.96is placed in a magnetic field directed perpendicular to the planeof the coil. The magnitude of the magnetic field varies in timeaccording to the expression B = a1 t + a2 t2 ,where a1 = 0.0421T/s, a2 = 0.0733 T/s2 areconstants, time t is in seconds and fieldB is in Tesla.
Find the magnitude of the induced emf in the coil at t = 9.11s.
Answer in units of V.
