Carbon and silver conductors

npepinnovations, maybe I typed it wtong. I know that power going through cables creates a magnetic field, I was trying to say that carbon used for electricity tends to creat less of a feild. This is why you use carbon spark plug wires if you have noise on your audio system.

Thanks,

The strength of the magenetic field caused by current is a function of current and rate of change of current, not the material. Carbon is used in automobile ignition circuits for other reasons than prevention of noise (which is caused by the 'static' caused by the sparks at the plugs not by the magnetic field in the ignition wires. The magnetic field in wires of the ignition system is very low because the current is very low, although the voltages are very high. Magnetism caused by current is not lower in Carbon conductors for the same current.

Well back to the question.Is carbon good or bad for power cords?

Now I understand. Sorry. Back to the question? I know first hand that silver makes a great power cable and IMO it works better for that than it does for audio cables. (except when everything is silver including the voice coils)
