A coil 4.15 cm radius, containing 560 turns, is placed in a uniform magnetic field that varies with time according to B=( 1.20×10−2 T/s )t+( 3.40×10−5 T/s4 )t4. The coil is connected to a 530-Ω resistor, and its plane is perpendicular to the magnetic field. You can ignore the resistance of the coil.
(a) Find the magnitude of the induced emf in the coil as a function of time.
(b) What is the current in the resistor at time t = 5.00 s?
