Question

What is the coefficient of coupling of the inductor?

Answer 1

1. When an electric current flows through it, an inductor, a two-terminal electronic component, stores energy in the magnetic field.
2. The coupling coefficient is defined as the fraction of the magnetic flux produced by the current in one coil that links with the current in the other coil.
3. It is represented by the symbol (k), and the coefficient of coupling is used to express the amount of coupling between two inductively coupled coils.
4. The coefficient of coupling is always less than one, and its maximum value is one. The perfect coupling occurs when the entire flux of one coil links the other and the coefficient of coupling has a value of one.
5. If the coefficient of coupling between two inductors is high, their mutual inductance will be high as well.
