the magnetic field around the adjacent pairs of wire
Four pairs
4 pairs of wires.
(1) the higher the twist, the higher the throughput (2) The higher the twist, the the lower the crosstalk
take fencing pliyers and twist the wire.
One application is when signal isolation is required. Twisted pair wire tends to self-shield for differential signals. This is because external interference induces equal currents in both conductors due to the symmetry of the twists. The differential input then cancels out the common-mode (equal on both wires) noise, allowing the desired differential signal to pass. One interesting example of this is UTP (CAT5, CAT6, etc.) cable used for ethernet cabling. If you strip the jacket off of a length of cable, you will notice (obviously) that the pairs are twisted. Look closely though, and you will notice that each pair is twisted with a different twist-per-inch than the other. If each pair had exactly the same twist, then the pairs cold 'line up' with each other, allowing crosstalk between the pairs (very bad). By varying the twist rate, crosstalk is minimized. In fact, the different twists are prime numbers, which means they never match up anywhere in the cable! Is that cool or what!
First twist together the wires to be joined. For larger wire use lineman's pliers to apply twist. Make the twist clockwise. Then twist on the wirenut clockwise on the wires. Wirenuts are rated as to how many wires of a certain size they can hold but in general twist by hand until you can twist no more and then about 1/2 twist with pliers. If the wirenut does not get tight it is too big or internal metal portion could be clogged in some way.
pull and twist on metal sleeve surrounding plug wire. Nope.. try to twist the boot to break the grasp.
CAT5 cable is actually not able to sustain 1Gbps transfer rates, as the two pairs that are used only for grounding in CAT5, and are used for signal in CAT6, are not controlled as tightly as is necessary for full throughput. A gigabit network, finding itself connected with CAT5 cable, will degrade itself to 300Mbps.
To install lock wire on bolt heads, first thread the wire through a hole in one bolt head, then twist the wire around itself to secure it. Next, thread the wire through the hole in the adjacent bolt head and wrap it around that bolt head as well. Finally, twist the ends of the wire together tightly to prevent the bolts from loosening.
