Chapter 37, Problem 42A

How could you move a conducting loop of wire through a magnetic field without inducing a voltage in the loop?

To determine

To explain: the process to bring motion in conducting loop using magnetic field with no induction of voltage

Answer to Problem 42A

The movement should be such that the field lines do not change.

Explanation of Solution

Introduction:

As the field line changes thee will be voltage induces in the coils.

The conducting loop of wire changes the magnetic field as during movement there will be a change in the number of field lines. If the number of field lines does not change then there will be no change in the magnetic field and the voltage does not induce in the coil. Thus, the movement of the coil in a way that the field lines do not change, the voltage will not induce in the coils.

Conclusion:

The movement of coils will not induce voltage if the number of field lines does not change.
