Mutual Inductance between Two Coils

Mutual inductance is the property of two coils in which a change in current in one coil induces an electromotive force in the other coil. The mutual inductance between two magnetically coupled coils depends on several factors, which are discussed below.

Factors Affecting Mutual Inductance

The following factors affect the mutual inductance between two magnetically coupled coils:

1. Permeability of the Core Material

The permeability of the core material affects the mutual inductance between two coils. The higher the permeability of the core material, the higher the mutual inductance between the two coils.

2. Number of Turns of the Coils

The number of turns of the coils affects the mutual inductance between two coils. The higher the number of turns of the coils, the higher the mutual inductance between the two coils.

3. Cross-Sectional Area of their Common Core

The cross-sectional area of the common core affects the mutual inductance between two coils. The larger the cross-sectional area of the common core, the higher the mutual inductance between the two coils.

Conclusion

In conclusion, the mutual inductance between two magnetically coupled coils depends on the permeability of the core material, the number of turns of the coils, and the cross-sectional area of their common core. Therefore, to calculate the mutual inductance between two coils, we need to consider these factors.
