Answer B

Part A A coil 4.20 cm radius, containing 420 turns, is placed in a uniform magnetic field that varies with time according to B =( 1.20x10-2 T/s )t+( Find the magnitude of the induced emf in the coil as a function of time. 2.70x10 5 T/s )ti. The coil is connected to a 700- S resistor, and its plane is perpendicular to the O E = 8.89x10-3 V +(8.00*10 5 V/s3 )+3 magnetic field. You can ignore the resistance of the coil. O E = 2.79x10-2 V +(6.28*10-5 V/$3 )+3 O E= 2.79x10-2 V +(2.51*10-4 V/s3 )+3 O E = 8.89x10 3 V +(2.51x10-4 V/s3 )+3 Submit Previous Answers Correct V Part B What is the current in the resistor at time to = 4.95 s ?
