yeah, you didnt? Thats why your antenna wires are shielded with tin foil like stuff, it is grounded, so if electromotive interference (EMI) is induced into that antenna wire (or whatever wire), the shielding grabs the voltage, and grounds it so it never reaches the antenna center wire. Much is the same for your ignition wires. They have no shielding, and lines of flux cannot be stopped, they are always there no matter what. These are how magnets attract themselves. In an effort to stop induction into wires, we twist or braid them. This is why a lot of the low voltage sensor wires are often twisted together, speed sensors and such, to stop voltage from being induced into another wire and sending a false signal. Did I confuse you? I doubt it, but hope this helps you a littly bit bheston.
