The effect on the wire itself that generates the electromagnetic field is called "self-inductance", which is the changing magnetic field generated by the wire itself, which produces a changing magnetic field that further influences the current in the wire; the effect on other wires in this electromagnetic field range It is called "mutual inductance". The electrical characteristics of the inductor are the opposite of the capacitor, "pass low frequency, block high frequency". High frequency signals encounter large resistance when passing through the inductor.
