A coil 4.05 cm radius, containing 510 turns, is placed in a uniform magnetic field that varies with time according to B=( 1.20×10−2 T/s )t+( 3.05×10−5 T/s4 )t4. The coil is connected to a 610-Ω resistor, and its plane is perpendicular to the magnetic field. You can ignore the resistance of the coil.
