Discussion Overview
The discussion centers on the detailed derivation of the inductance effect in coiled wires, exploring the magnetic influence of current elements on each other. Participants seek references and methods for understanding this phenomenon, including theoretical and empirical approaches.
Discussion Character
- Exploratory, Technical explanation, Conceptual clarification
Main Points Raised
- DaTario requests references for a detailed derivation of the inductance effect starting from the magnetic influence of current elements.
- One participant explains that for a long solenoidal shape, the magnetic field can be calculated using Ampere's law, leading to the computation of magnetic flux and inductance, but notes that the general case is complex.
- Another participant mentions the Wheeler empirical formula as a commonly used reference and provides links to discussions on high-frequency characteristics and self-resonance in coils.
- DaTario inquires about the outline of the derivation, suggesting it should involve a self-consistent method similar to the Hartree-Fock method.
Areas of Agreement / Disagreement
Participants express varying levels of understanding and reference different methods, indicating that multiple approaches and models are being considered without a consensus on a single derivation method.
Contextual Notes
The discussion highlights the complexity of deriving inductance in general cases and the potential need for specific methods or approximations, which remain unresolved.
