If a homogenous disk of "proper proportions" of silver, gold and platinum were made the subject of magnetic interference in an alternating field, the molecular antagonistic thirds would cause a very erratic gyroscopic movement.

Differentiation of sympathetic flow, (i.e., interference) as through a homogenous wire, can be equated in the same manner as in the trexar. Two differing molecular densities of the proper ratio will harmoniously adjust chords of that ratio, i.e., a ratio of 1:3 will adjust thirds, 1:4 will adjust fourths, 1:7 will adjust sevenths, etc.
