Looks like a good start. Thanks for mentioning the term "bucking coil" since the exact words move far better through the search tools.

Such a coil can be made two ways:
1. Fields cancel and so does electron drift.
2. Fields cancel but electron drift adds.

This is an interesting piece, pointing out that the different diameter of coils will produce a differential inductance even though the number of turns on both coils is equal.

Yet it is possible to completely cancel the inductance with a dual winding on a single layer, and I think there are other ways to do it as well. For example one could wind 4 layers such that the center of the windings is a point midway between the second and third layer, and the winding symmetry would be designed around this center such that the inductance cancels.

This would leave the electron drift as a variable feature of the design, so that we would still be able to wind two versions of this coil.

Coil 1: Inductance cancels but electron drift does not.
Coil 2: Inductance cancels and electron drift cancels.

It might be possible to wind the coil in sections so that a single device could be set up to have no electron drift, or to have electron drift (always with inductance cancelling). This might be accomplished by switching the way several layers are interconnected. Such a device would allow extremely precise measurements to be made because there would be no issues with device-to-device variation.

So I still wonder if anyone has investigated this electron drift idea. Apparently no one has.
