What is inductive coupling? Let’s talk about the principle.

Inductive coupling refers to an electromagnetic induction effect between lightning and cables.

Coupling is also called "cross-connection". The coupling phenomenon is the phenomenon that when two or more circuits form a network, the current or voltage of one of the circuits changes, which affects the corresponding changes of other circuits. That is to say, the energy (or information) of a certain circuit is transmitted to other circuits through coupling. In electronic amplification circuits, the cross-connection between stages is achieved by coupling circuits. The condition for realizing coupling is that there must be a common impedance between circuits. According to the nature of the public impedance, the coupling circuit is divided into various forms such as resistive coupling, capacitive coupling, inductive coupling, resistive capacitive coupling and mutual inductance (transformer) coupling.
