From the point of view of inductance, inductance is multiplied, magnetic chain represents the total magnetic flux, the common-mode inductor, when magnetic flux is doubled, circle number has not changed, the current didn't also did not change, so mean increased inductance for 2 times, means that the equivalent permeability into 2 times.

Common-mode inductor in common mode, therefore, when an electric current passes through, work under the mutual inductance model, under the effect of mutual inductance, the equivalent inductance is cost increase, therefore common mode impedance will be multiplied, and the common mode signal has good filtering effect, also is the common mode signal with large impedance block, don't let it pass the common-mode inductor, also is not to let this signal transmission to the next level of the circuit, the following is the inductive reactance ZL.
Know common-mode inductor under the mode of common mode inductance, is the main clue to know mutual inductance, magnetic components of all, no matter what name as long as mastering the form of the change of the magnetic field, magnetic field changes through the phenomenon to essence, also easy to understand, moreover we always grasp the magnetic field lines, it is our understanding the visual form of the magnetic field, consider whether the same side or different name or concept of the mutual inductance phenomenon or magnetic field, we are drawing the lines of magnetic force to realize their - master "magnet winding method" is explained before.
