A coil 3.85 cm in radius, containing 520 turns, is placed in auniform magnetic field that varies with time according to B=(1.20×10^−2 T/s )t+( 2.70×10^−5 T/s^4 )t^4. The coil is connected toa 580 Ω resistor, and its plane is perpendicular to the magneticfield. You can ignore the resistance of the coil.
1. Find the magnitude of the induced emf in the coil as afunction of time.
2. What is the current in the resistor attime t0 = 5.30 s?
