What the patent actually fixes
The core MWO patent, US1962565A, fixes the general architecture more clearly than it fixes a universal build recipe. It describes open radiating circuits: concentric insulated split rings of different diameters, with gaps and terminal details that contribute to each circuit's inductance and capacitance.
That matters for "Lakhovsky coil dimensions" searches. A single copper ring, bracelet, or modern cabinet layout may be inspired by the patent, but it should not be presented as the original device unless the dimensions are traced to a specific patent drawing, manual, measured artifact, or contemporaneous document.
Diameter, gap, and wire are coupled
Diameter changes the loop area and inductance. Wire diameter changes conductor radius and resistance. Gap geometry and nearby terminals affect capacitance. Supports, neighboring rings, the enclosure, the driving transformer, and nearby bodies or conductors can shift the measured behavior.
This is why a single list of dimensions is not enough. Even if two rings share the same diameter, their resonance can change when the gap terminals, mounting, and surrounding structure change.
Use the calculator as a sanity check
The open-ring coil geometry calculator estimates copper length, loop inductance, gap capacitance, and a lumped LC resonance for one isolated ring. It is useful for understanding the direction of the physics. It is not a replacement for measurement, electromagnetic simulation, or historical provenance.
How to label modern dimension claims
