Chapter 4: Q3DQ (page 1012)

In Figure below, if coil2 is turned90° so that its axis is vertical,

does the mutual inductance increase or decrease? Explain.

Short Answer

Expert verified

Answer

The mutual inductance is decrease

Step by step solution

01

Definition of inductance

The term inductance may be defined as the property of electrical circuit to oppose a change in the electric current flowing through it.

02

Determine mutual inductance increase and decrease

The mutual inductance of coils is proportional to the coupling factor. When turn the coil decrease in coupling factor. There is no magnetic flux coupled if coilsperpendicular to each other.

Hence, the mutual inductance is decrease.
