The graphical layout of this article looks terrible, but all the various positions I've tried for the figure and table still give a result that looks bad. Alison Chaiken 21:07, 18 February 2006 (UTC)
Should the reference to the nanoparticles be a hyperlink in the table or is a listing at the end preferable? If in the table, some notation should be made to indicate nanoparticles rather than bulk or film. Alison Chaiken 00:10, 9 March 2006 (UTC)
There are no units on the coercivity tables. I don't have access to a lot of the references, so I can't verify the units by myself. Can anybody help? -- 128.213.17.91, 17:53, 10 August 2006
Now the table has units, but they are non-SI units. According to the Wikipedia Manual of Style WP:UNITS, since this is a scientific article, and the table is not a direct quote, the coercivity values should be given in amperes per metre (A/m), not oersteds (Oe).

The .05 value for iron is wrong -- I don't know where the author of the referenced article got it from. Silicon Irons, which have lower corcivity than plain iron, run between .4 and .9 oersted (and the article referenced actually says this). The actual value, as far as I can determine, is around 2 oersted. I've updated the article. Ahecht ( talk) 15:27, 20 May 2008 (UTC)
Would it be useful to replace the second hysterisis loop graphic with a graphic of a soft magnetic materiel so people can see the difference between a high and low coercivity materiel? 32.145.11.31 ( talk) 19:17, 9 December 2008 (UTC)
We have a difference of opinion on whether the table of coercivities should be collapsed. I believe that most readers will not care about these numbers, and the part they want to read is squeezed between the table and figures. If anyone does care, one click will give them the information. Anyone else want to weigh in? RockMagnetist ( talk) 01:23, 4 January 2011 (UTC)
Hello fellow Wikipedians,
I have just added archive links to 2 external links on
Coercivity. Please take a moment to review
my edit. If necessary, add {{
cbignore}}
after the link to keep me from modifying it. Alternatively, you can add {{
nobots|deny=InternetArchiveBot}}
to keep me off the page altogether. I made the following changes:
When you have finished reviewing my changes, please set the checked parameter below to true to let others know.
An editor has reviewed this edit and fixed any errors that were found.

Please check intrinsic vs normal coercivity in the tables. They may be intrinsic. Jmv2009 ( talk) 18:26, 25 February 2020 (UTC)
I found the normal / intrinsic thing to be a bit confusing. I think it doesn't help that there are many "B vs H" curves that are actually plots of vs H. This latter quantity is often given the label J (not to be confused with electric current density): https://www.magnet-sdm.com/2017/06/19/hysteresis-loop-demagnetization-curve-magnet/ . What's odd is that some people do magnetics without referring to magnetization at all. Example: [1], where they only use the term "intrinsic induction", referring to (which is precisely , or J). Then to make matters worse there is the whole confusion of gaussian electromagnetism vs SI electromagnetism.
So to be clear, my understanding is:
If this is correct then the current article is wrong since it seemingly states the second definition for the first term. The article also needs a better graph, showing a high-coercivity material where the difference matters.

I work with magnets, and the coercivity values in the table are orders of magnitude off. For soft magnets typical values are ~1-100A/m, not a million or so times below that.
