Advantage and disadvantage of twisted pair cable coxial cable and fiber optic cable?

The twisting of wires reduce crosstalk because when electrical current flows through a wire, it creates a small, circular magnetic field around the wire. When two wires in an electrical circuit are placed close together, their magnetic fields are the exact opposite of each other. Thus, the two magnetic fields cancel each other out. They also cancel out any outside magnetic fields. Twisting the wires can enhance this cancellation effect.
