I would not be convinced that any shielding is taking place until I completely "shielded" the internal loop.
If one could devise a way of getting some indication that the loop has current, or does not, then one would know with 100% certainty shielding is taking place.
One idea might be to fully encase a wire loop where the wire loop terminates on a very small piezo buzzer. Anything that can make an audible noise would work. I'm sure there are other ideas that could work.
Is this a conclusive test? If there is no current, is this because shielding is taking place, or is there no current because of the big shorted ring?
OR, if there IS still current, is that because there is no shielding, or is it because of coupling between the shorted ring and the inner loop?
I suspect that even with 100% coverage of the "shield", an emf would still be induced in the inner loop. In other words, the so-called "shielding" in this case is not effective. This means that either the E field is inducing the current at the wire segment threading the toroid (as already proposed), or there is another elusive penetrating field or potential responsible for the induction (the Magnetic Vector Potential, A Field?)
Also, there is much talk about the toroid's E field making its way around to other parts of the loop to cause the induced emf. May I ask you to draw out your vision of what the E field looks like around the toroid coil and associated wire loop?
