The magnitude of the magnetic field in a certain region is represented by the equation |B| = at + bt + c, where a = 0.035 T/s, b = 0.040 T/s and c= 0.168 T. A circular coil with 55 turns and diameter 12.5 cm is placed in this region with its plane perpendicular to the direction of the magnetic field. What is the magnitude of the induced emf at t = 1.50 s? mv
