Wire inductance L[henry] is real = how a speaker coil works.
A magnet moving through a coil of wire makes electricity & vice / versa.
This is why a balanced signal consists of a twisted pair ;
the pos & neg twisted together porduce opposite magnetic fields via the right hand rule.
(Grab an insulated wire with you thumb in the direction of electron flow ;
then your fingers wrap around the wire in the direction of the induced magnetic field.)
Additionally , the braided shield protects a signal wire from external Radio Frequency interference.
