Field coupling coefficient

Coupling coefficient. The coupling coefficient is the ratio of the open-circuit actual voltage ratio to the ratio that would be obtained if all the flux coupled from one magnetic circuit to the other. The coupling coefficient is related to mutual inductance and self inductances in the following way. See more Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The flow of electric current creates a magnetic field around the conductor. The field strength depends on the … See more A current $${\displaystyle i}$$ flowing through a conductor generates a magnetic field around the conductor, which is described by Ampere's circuital law. The total magnetic flux $${\displaystyle \Phi }$$ through a circuit is equal to the product of the perpendicular … See more In the most general case, inductance can be calculated from Maxwell's equations.
