Talk:Remanence

Old unsectioned comments

This is wonderful.

May I suggest a link to the 'paleomagnitism' page that is located elsewhere in Wikipeida.

Thanks,

You could have added that yourself. Just put 2 square opening brackets and 2 square closing brackets roun the word you want to link like this. PS. dont forget to sign and date your posts by using 4 tildes.

Rating of article

I have rated this article mid-importance (same as coercivity). RockMagnetist (talk) 14:42, 12 September 2010 (UTC)

Merger discussion

As far as I can tell from its uses in peer-reviewed articles, Retentivity is a synonym for Remanence. If a distinction is drawn, retentivity is measured in units of magnetic flux while remanence is measured in units of magnetization. However, a disambiguation page might be appropriate if Wikipedia pages exist for non-physics meanings. RockMagnetist (talk) 21:34, 22 September 2010 (UTC)

Hi again :) Merge it, I've chopped the unsourced humanology bit as WP:ORish as well as off topic. Vsmith (talk) 02:05, 23 September 2010 (UTC)

Done. RockMagnetist (talk) 02:26, 23 September 2010 (UTC)

Colloquialism

How this property differs from a permanent magnetic field, or how it is similar or that it is identical is not mentioned. Since a permanent magnetic field seems to have the same definition is this word, and this article has no reference to the term's etymology, I'm questioning the need for an article rather than a reference to a Wiktionary entry, as a a synonym for "magnetic field".

The term seems to be either an undesired residual (permanent) field created as a side effect to current flow or induced previously by a nearby permanent mag field, or as an induced and desired field such as that found on magnetic media. Perhaps it is a colloquialism used in information technology (and related fields). Likewise it may be a term used ubiquitously in Electricity and Magnetism theory that I've just not seen before. Can someone provide verifiable information to answer this?

I fail to see how you came to the conclusion that it is a colloquialism - have you read the whole article? Remanence is an important technical term used by people who study magnetism. It is true that it can be an important tool or a nuisance, depending on the application, but the people discussing "remanence" and "residual magnetization" are referring to the same phenomenon. As for verifiable information, there are several authoritative citations. In particular, the two books by Chikazumi and Bozorth are two of the most highly respected references on magnetism. So please read some of the literature before you start wiping out large chunks of the text.RockMagnetist (talk) 02:03, 1 April 2011 (UTC)

I can't explain why I made changes here -- I apologize and can't recall what prompted me to do that.

However the article on Data Remanence might have been the article of interest. Would you consider looking at that article (and at the Discussion page)? That article, I think, needs assistance from someone whose preference is magnetism (rather than IT). It seems like an example of remanence -- not different from it. Questions I think that article ought to answer: Can differences be distinguished in the analog representations of two different bits that have the same value; and can visualized differences be traced to previous values stored. (A possible technique is electron microscopy). Kernel.package (talk) 02:43, 10 October 2011 (UTC)

Impact-induced magnetism

I wonder if the lead-in should mention impact-induced magnetism as well. It notes induced magnetism through the subjection of an external magnetic field however many "natural" magnets were created through impacts, either from meteorites or ejecta from volcanoes.
