← Two coils have a mutual inductance of 18 mH. The current in the first coil falls steadily from 4.1 A to 1.9 A in 3.0 ms. What is the average emf in the second coil?An alternator has one coil on its rotor, and its output reverses 100 times every second. At what rate must the rotor be driven, in revolutions each minute? →
