In a multi layered coil wrapped around a ferromagnetic core, is all the flux through the core linked to all the layers of coil equally or does the flux decrease for the outer layers? — Preceding unsigned comment added by Thecoolsundar (talk • contribs) 08:58, 28 April 2016 (UTC)[reply]

Outer (towards the ends) turns of a single-layer solenoid coil will link less flux than inner turns. The difference will be negligible with typical cores, probably ~1:10K or even as little as ~1:1M, depending on the core material. Even with an "air" core, the difference will still be pretty small for a tight solenoid. In a multi-layered coil, an outer (towards the larger radius) turn will link all the flux linked by an underlying inner turn, and then some -- i.e. outer (towards the larger radius) layers will tend to link more flux than inner layers.

Flux can be understood if it is heard in an analog synth instrument that has a VCF with the FLUX filtering the patch. Synth players are manipulating voltage by using principles of flux to create resistance in how waves perform with a delayed pulse that comes back on itself. — Preceding unsigned comment added by WikiFikiFool (talk • contribs) 17:32, 21 September 2016 (UTC)[reply]

This is really a lot simpler than this article makes out

Chua's notion of memristor and integral of voltage is really quite tangential to the usual usage of this term. It just means lines of flux that have linked to something else, a conductor for instance. Simples. SpinningSpark 19:57, 12 October 2019 (UTC)[reply]

Indeed, here's a clearheaded IEC definition for linked flux (which I assume is the same concept as flux linkage). It is defined as a special case of magnetic flux, not as an extension of the concept. The article is currently very confusing and should be edited. --Jähmefyysikko (talk) 13:10, 10 March 2022 (UTC)[reply]

In particular, one should start from the common, widely accepted use of the term, and discuss the less standard usage only later in the text. --Jähmefyysikko (talk) 13:14, 10 March 2022 (UTC)[reply]

That just seems common sense to me. Isn't that what schools have done for some time? Start off with a simpler, but less descriptive/accurate model or explanation of a topic.

Then, perhaps in year 2, you learn that the previous explanation wasn't the whole story and are given a more complete but also more complex and less "user friendly" model while discussing the shortcomings of the previous one. Rinse, repeat until PhD.

This is even one of the first things that Richard Feynman disusses in his lecture series.

I mean, you don't teach a child to multiply before they know how to count. You start sinple, and build your way up. Otherwise we'd have a lot more confused 6 year olds in college. 2607:FEA8:99C0:61C0:65A1:D950:9533:9036 (talk) 19:53, 22 March 2023 (UTC)[reply]

Flux linkage definition should start not from the integral, but from magnetic flux (this is where the integral actually comes from). We should assume here that the reader understands what the flux is (or have read the article). Flux is hard to understand, but the linkage itself is near-trivial. I will start rewriting the article along these lines. Викидим (talk) 19:00, 3 July 2023 (UTC)[reply]

Rewrote the lead to reflect the trivial EE view of the linkage. Left the rest as-is, although it is, in my opinion, WP:UNDUE, as the term is almost exclusively used in the theory of electric machines. Викидим (talk) 20:00, 3 July 2023 (UTC)[reply]
