Hello, I'm Constant314. I wanted to let you know that one or more of your recent contributions&#32;to Inductance have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Teahouse or the Help desk. Thanks. Constant314 (talk) 18:02, 31 July 2022 (UTC)


 * Hi Constant314,
 * The first sentence: Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. Is not correct.  Inductance has nothing to do with changes with respect to time.  However, impedance does. The sentence describes impedance exactly, not inductance.
 * My proof: Looks at the units for inductance on the Wiki page.  It says:
 * L = Φ / I Inductance is not a function of time.
 * In words this says inductance is the ratio of flux to current. Time does not affect inductance.  This applies to both DC and AC. Yes, alternating current can change as a function of time but this does not affect inductance because the flux change in sync with time too, thereby nulling out any respective change.
 * Further, based on the first sentence one would conclude inductance does not exist for direct current circuits because the current is constant. Inductance applies to DC as well.
 * One of my professors in college always said look at the units to better understand that nature of a physical property.
 * The problem is that the words induction and inductance sound similar and tend to get confused. Induction include time and inductance does not.
 * I hope this helps.

 * The point that you are missing is that the article is about inductance and not about impedance. The first line of the lede is used to define the subject of the article.  You are welcome to improve the definition, but not change the subject of the definition. Constant314 (talk) 01:08, 1 August 2022 (UTC)
 * Constant314,
 * Per your response:
 * You are welcome to improve the definition, but not change the subject of the definition.
 * OK, my recommended change is:
 * From: "Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it."
 * Actually, the above defines impedance, not inductance.
 * To:"Inductance is a measure of the magnetic field generated around a conductor in relation to the magnitude of current flowing through the conductor. In other words, the greater the magnetic field around a conductor for a given level of current, the higher the inductance."
 * My proof is simply look at the relationship on the wiki page:
 * L = Φ / I Typically, this is Weber per Ampere.  As I said before: time is not a factor for inductance but is for impedance.
 * I hope this helps and will improve the readers understanding of inductance.
 * Thanks! 98.171.14.251 (talk) 15:10, 1 August 2022 (UTC)
 * There is some merit in that. I was thinking of adding something like that to the definition.  You should open a discussion on the talk page of the article, so that others can join in.  Some comments, however:
 * The definition doesn't have to be this or that . It can be this and that .  In other words, you can add a second definition.
 * We try to write the lede at a 9th grad reading level, although it isn't always possible.
 * I don't like the word "measure" in this context. It is a little bit obscure for a 9th grade reader.  I was think that proportionality constant or coupling coefficient between current and total magnetic flux might be better.
 * Let's continue this discussion on the talk page of the article. Use the tab at the top to start a new discussion. Constant314 (talk) 18:08, 1 August 2022 (UTC)
 * Constant314,
 * I looked at the Wiki page Henry(unit). Whoever wrote it did a great job!
 * Interesting how some things on Wiki nail it and others don't.
 * I have worked around electrical things all my life. I am an licensed electrical engineer in Arizona and not a lawyer and really don't like proving to others the basics of physics.  As I said earlier inductance and induction are commonly used incorrectly.  I can see how this is easily confused.
 * Thanks for your suggestion, but I probably will not take the challenge you suggested to fix this.
 * All the Best! 98.171.14.251 (talk) 00:59, 2 August 2022 (UTC)
 * I am also a PE (retired) EE. It is a constant challenge to write at a general level and yet still avoid telling lies to children. Constant314 (talk) 03:08, 2 August 2022 (UTC)
