The emf developed in a coil X due to the current in a neighboring coil Y is proportional to the:
A)magnetic field in X
B)rate of change of magnetic field in X
C)resistance of X
D)thickness of the wire in X
E)current in Y

Question

Quizplus · Accepted Answer

The emf induced in a coil is calculated by the rate of change of magnetic flux through the area enclosed by the coil. This can also be expressed as the rate of change of magnetic field in the coil. Therefore, the emf developed in coil X due to the current in coil Y is proportional to the rate of change of magnetic field in X.
