I always wonder what we don't yet know about magnets and magnetism. At some point down the road scientists might discover that they cure diseases, provide unlimted power, nullify gravity, or something else really cool like that. And I'll be dead and won't get to see it.
JohnK, Yep, good catch. I was writing, and thinking about the signal as a positive half and a negative half. I plopped .707 into equasion to calculate peak voltage instead of 1.414 to get peak to to peak for the whole cycle. I plead "guilty with an excuse" - It was after midnight, and there were a few containment errors with some of the beer bottles around here earlier that night.
The article that you mention is correct, but it really has nothing in common with what I am talking about. It states "
The low impedance of the circuit also tips the balance of concern from capacitance, which is important in interconnect use, to inductance, which, while a concern, can be controlled only to a limited degree. "
The "inductance" that the article is talking about is the electrical behavior of a coil of wire in resisting any change of electric current through the coil. A capacitor has "capacitance" which is the behavior of a capacitor in resisting any change in voltage. All cable, wire, etc. has some of each because they are unwanted properties that are unfortunately, laws of nature. They simply can't be removed. Mother Nature won't let them.
An inductor is a coil of wire (some wound around tubular cores, others around donut shaped cores depending on the inductance rating).
What I was referring to was "induced voltage". Whenever any piece of held stationary inside of a changing magnetic field, some voltage will be induced into that wire. It is another one of those laws of nature.
