I have a fair enough grasp of electromagnetic induction to explain transformers and speakers to a lay person. But I recently tried to explain induction between two parallel wires, and realized that I don't have the practical experience to really internalize the strength of the effect. I've read a few posts related to the issue, and I've used the calculator available on this site, but knowing the change in magnetic flux or amount of inductance in Henrys or Webers doesn't help me. 
I need to know amps and volts.
My general understanding is that inductance between two parallel copper wires (from wire 1 to wire 2) is better: the higher the frequency in wire 1, the faster the change in current of wire 1, the larger wire 1 is than wire 2, the closer together the wires are, the less the shielding between the two but the greater the shielding around the pair, the longer the wires are (perhaps even coiling wire 2 around wire 1), and having wire 2 *not* be the return path of wire 1, but rather it's own circuit. And from what I can glean, even with very long wires, a strong current at a high frequency in wire 1, and a large and rapid change of the current in wire 1, the current in wire 2 would still be super small.
So my first question is: do I seem to have the basics down, or am I missing something important?
My second question is the biggie: is anyone interested in walking me through a real-world example, in units I know, within the ranges I understand? I don't work with circuit boards or high tension lines. :)
To me, that means using standard US wall outlet current for wire 1... say, 15 amps, 110 volts, 60 hertz, a diameter of 8 to 26 gauge, and whatever finite length is required. For wire 2, I want to assume it's a separate circuit (not the return for wire 1, as I think that complicates it), a diameter of 8-26 gauge, and coiled around wire 1 if necessary (but hopefully not). Both circuits can use multimeters as their load, or anything else that makes the example nice and simple, and we can assume that their return wires will not interfere. We can vary the diameter, length and distance between the wires. And we can even introduce basic electronics, like a frequency changer or amplitude modulator.
I know the resulting current in wire 2 will be small, but is it possible to adjust any of the input parameters to induce a current that I would encounter in everyday life? Perhaps a few hundred milliamps and a few volts. Anything smaller than that and it becomes imaginary to me again.
I know this is a lot, and probably very tedious, so ignore this post unless it piques a particular interest.
Thanks in advance.
