What is a Magnetic Coupling Coefficient?

The magnetic coupling coefficient, often denoted as k, is a dimensionless parameter that quantifies the degree of magnetic coupling between two inductors. It ranges from 0 to 1, where 0 indicates no coupling and 1 indicates perfect coupling. This coefficient is crucial in transformer design and other applications involving inductive coupling, as it affects the efficiency and performance of the system. The value of k depends on factors such as the distance between the inductors, their orientation, and the magnetic permeability of the medium between them.

Example Calculation

Let's assume the following values:

Using the formula to calculate the magnetic coupling coefficient:

k=0.523=0.560.2041

The magnetic coupling coefficient is approximately 0.2041.
