Talk:Inductor
From Academic Kids
Just a layperson, trying to disambiguate coil -- should the currently non-existent induction coil be a separate article, or redirect here? or vice versa? Catherine 00:29 Apr 14, 2003 (UTC)
Why is "L" the symbol for inductance? - Joseph D. Rudmin
You mean the variable (The unit is usually Henrys.)? "I" was already taken for current; "i" for the square root of -1; not sure where L came from but I suppose it makes as much sense as anything. UninvitedCompany 19:49, 17 Feb 2004 (UTC)
Yes; how embarrassing! I know the difference between symbol and unit. I have corrected my question. - Joseph D. Rudmin
It's spelled characteristic.
Why did you move inductance to its own article? I think it is better in the inductor article with inductance as a redirect. They are essentially the same thing and should be in one article. Whether inductor or inductance I don't know, but the two belong together. That's like separating running from runner. An inductor (parasitic or otherwise), and nothing else, has inductance and inductance is a property of inductors. - Omegatron 16:58, Apr 13, 2004 (UTC)
At the very least, equations should be moved to inductance, and actual information on construction, etc. to inductor.
- Why? They are both about the same thing. A "parasitic inductor" is still an inductor, right? And you don't construct those. Maybe there is no such thing, and there is only "parasitic inductance"? - Omegatron 19:32, Oct 18, 2004 (UTC)
Induction loop
I suspect that the new Induction loop article needs to be merged with another (this one?); it certianly needs a lot of work by someone who knows what they're doing. Mel Etitis (Μελ Ετητης) 13:12, 30 Mar 2005 (UTC)
- No kidding; Is there much in that article that's salvagable?
- And shouldn't it be about the gadgets used to tap phones and detect cars at traffic signals?

Deletion of old history section
I had hopped to save some bandwidth but if I must: First, it is wrong. Stanley didn’t invent the first practical induction coil as stated. Inductions coils had been around for fifty years before that and Ruhmkorff was building excellent ones in 1850. What Stanley’s patent did cover was a version of an AC transformer that proved to be practical and similar to modern transformers. Since patents require titles and there was not yet a word for the device, he used whatever words were handy. The patent was titled “Induction Coil”. Mr. Stanley’s contribution is covered in transformer where it belongs. It has nothing to do with the Inductor article. This history section was left over here as a remnant of some confusion in terminology from a year ago. Let us recreate a history section only when we have something applicable to put into it.

- Thank you for that explanation.
