The pairs are twisted to provide protection against crosstalk, the noise generated by adjacent pairs. When electrical current flows through a wire, it creates a small, circular magnetic field around the wire. ... Thus, the two magnetic fields cancel each other out. They also cancel out any outside magnetic fields
