Atmosphere, please don’t tell me you think that "near light speed" means light speed? I just finished explaining for the umpteenth time that the velocity of light and any electromagnetic wave depends on the medium through which it travels. I’m having trouble deciding if you have a propensity for density or if you’re just pretending. ;-) Let me make myself a little clearer just in case my first three or four attempts were not clear enough. The speed of electromagnetic waves in a vacuum is what 186,000 miles per second, right? And in a conductor it is a large fraction of c, let’s say it’s 80% of c or about 150,000 miles per second. That’s close to c, and that’s why I refer to it as "near light speed." Follow?
I also did not say the electromagnetic wave in the cable can't be influenced by external magnetic fields. You are not only putting words in my mouth but you obviously *missed the whole point* of my discussion of the subject lo these past few days.
