I know quite a bit about electromagnetism, and this article escapes me. Suppose I don't know anything? This article needs rewritten to make it accessible, and in a way amenable to experiment so someone can see what it means in practice. Sbalfour (talk) 15:57, 22 November 2017 (UTC)Reply
Glad you caught this. I have a BS in electrical engineering and I don't understand it either. However I googled a bunch of the terms and I think I have a vague idea what it's about. This seems to be a quantity used in a technique for analysing magnetic circuits which is based on an analogy with electrical circuits. It might be the Gyrator-capacitor_model. The WP article Magnetic circuit describes how, due to Hopkinson's law, in closed-loop magnetic circuits magnetomotive force (MMF) acts analogously to a voltage, magnetic flux acts like a current, and reluctance acts like a resistance. Apparently "magnetic reactance" is a quantity in magnetic circuits analogous to electrical reactance in electric circuits. (This is just my impression; I could be all wrong.) The same guy created the articles Magnetic impedance, Magnetic effective resistance, Magnetic inductance and Magnetic capacitivity, which are apparently analogs of impedance, resistance, inductance and capacitance.
As you say, the article needs some kind of cleanup. So far I can't find any real explanations of this stuff on the web. This article's only sources are books in foreign languages from 1959, 1960, and 1985, which makes me question whether this is a legitimate analysis technique and, even if so, whether these terms are WP:NOTABLE enough to have articles on WP. I would think if it is, these quantities would be mentioned somewhere in the vast electronics literature on the web. Maybe all the above articles should be merged into Gyrator-capacitor model, and magnetic reactance, magnetic capacitivity, etc. should just be briefly defined in that article. What do you think? Another problem is that the term "magnetic reactance" was apparently used in the early 1900s for two other quantities in ordinary electrical theory: inductive reactance and the reciprocal of reluctance[1] --ChetvornoTALK08:31, 23 November 2017 (UTC)Reply
