How the copper rings and rods behind sacredcubit.com are made, what the physics of a closed copper loop actually says, and how to measure a ring's resonance yourself with a NanoVNA.
A ring starts as two lengths of 99.9% copper wire twisted together. The pair is bent into a circle and the ends are soldered, so the finished ring is a closed conducting loop. Four numbers define it, and all four are recorded for every ring:
| Parameter | Why it matters |
|---|---|
| Wire length before twisting | The cubit length the design is based on |
| Twist pitch (length of one full twist) | Tighter twists use up more wire |
| Finished circumference | Sets the loop's own resonances |
| Wire gauge | Thicker wire shifts resonance and uses more length per twist |
Each wire in a twisted pair follows a helix, so the pair ends up shorter than the wire that went into it. For wire diameter d and twist pitch p, the finished length is the wire length times:
p / √(p² + (π d)²)
For a 52.32 cm wire:
| Gauge | Factor, 10 mm pitch | Finished length | Factor, 15 mm pitch | Finished length |
|---|---|---|---|---|
| 12 AWG (2.05 mm) | 0.840 | 44.0 cm | 0.919 | 48.1 cm |
| 14 AWG (1.63 mm) | 0.890 | 46.6 cm | 0.946 | 49.5 cm |
| 16 AWG (1.29 mm) | 0.927 | 48.5 cm | 0.965 | 50.5 cm |
So a "52.32 cm ring" has to say whether 52.32 cm is the wire length or the finished length. Our specification always gives both. The table uses 10 mm and 15 mm as example pitches.
Induction. Faraday's law says a changing magnetic flux through a loop induces a voltage around it, EMF = −dΦ/dt. Because a ring is closed, that voltage drives a current around the ring. A ring does nothing on its own: it responds to fields that change.
Twisting. In a twisted pair, the wire nearest to an outside source swaps on every half twist, so both wires pick up nearly the same interference and it cancels in the difference between them. This is why network cables are twisted (Twisted pair, Wikipedia). The ring as a whole still encloses an area, so a field passing through the ring still induces a current around it.
Resonance. Like any conductor, a ring has resonant frequencies set mainly by its length. A single closed loop first resonates when its circumference is about one wavelength; antenna builders cut a full-wave loop to 1005 / f feet (IW5EDI), about 306 / f metres. A twisted pair is a more complex structure, so its resonances have to be measured, not assumed.
Whether rings at these sizes have measurable effects beyond ordinary electromagnetism is an open research question. Protocols and results, including null results, are published on 5D Library.
