Talk:Galvanometer

message: ... because most of what was there is already wikilinked in the article itself. And I don't see why a galvanometer article should have a see also about electrical quackery? I did leave the interwikis that an anon editor deleted. --Janke | Talk 18:44, 24 October 2005 (UTC)

message: I just came across this article about Galvanometers, and am surprised to see that the discussion still remains open. Someone previously wondered as to whether "those pretty equations would apply to all galvanometers containing coils, or are they just applicable to Tangent galvanometers?" The answer is that it's relative. If the equations contain the value Bh, then only an instrument which is effected by the magnetic field of the earth would require their usage. And yes, all things are effected by the earth's magnetic field, and gravity, but the question has to do with whether that effect is negligible in relationship to the usage.
Someone else referred to the Tangent Galvanometer as being "electrical quackery". Now there's not a lot of detail concerning the TG, but that does not make it fraudulent. My initial interpretation is that the coil forms an electro-magnet, and by its vertical rotation and proximity to the compass, while perpendicular to the horizontal plane, suggests that it might have some basis in scientific fact. If you could use an opposing magnetic field to cancel or divert the position of a compass' needle, you might be able to calculate for the strength of the magnetic field of the earth at that specific longitude and latitude by identifying Theta and the Current used by the coil. Whether the wirewound coil actually needs a non-magnetic core, or air core might be irrelevant to the equations. However, I have neither tried to build one, or have any intention or time to do so.
With that said, it seems to me that the best solution is to not link the two articles together at this particular point in time. There is no provided explanation as to why one might need to use a Tangent Galvanometer, outside of a Physics Lab experiment, and no history which makes reference to its creator. If there is no history and no modern purpose, or even an indication to a modern derivative of the device, it should only be considered valid as a possible, and perhaps plausible experiment in understanding the earth's magnetic field. All of this is to say that there should be no reason to continue with this discussion at this time, and the link should not be included, provided that if more information is later added to the Tangent Galvonmeter which merits a re-opening of the discussion, one should comply. --Theaudiodog 23:07, 10 May 2007 (UTC)

message: we are doing a science project for 9th grade and our teacher showed us a galvanometer. we obvsered that there were no units on the thing and that is our homework for tonight. any help? —The preceding unsigned comment was added by 216.54.156.245 (talk) 00:30, 9 January 2007 (UTC)

message: IEEE reference says Johan Jakob Nervander designed the more- sensitive Tangent galvanometer in 1834 but currently there is no mention of it in the article. Also I noticed that the article Tangent galvanometer was merged with this article. If there exists an independent history of the instrument Tangent galvanometer then I think it is perfectly possible to make that a separate article. The Legend of Zorro 08:07, 9 July 2013 (UTC)

message: I am wondering if this page should include a discussion of Galvanism. The excitement over the Voltaic pile in Europe preceded Ørsted's discovery.

replies: text: Mmm, probably not, in my opinion - do we have Galvanism? Preview shows a blue link there. The aim of Wikipedia is to be the world's parts catalog, so a discussion of social issues or why anyone cared about this device is not going to fit here.  --Wtshymanski (talk) 16:14, 17 July 2017 (UTC)
replies: text: That's a rather unhelpful response (and utterly confusing to those who have not come across your brand of sarcasm before).  The article already (in the lead) mentions Galvani and the frog galvanoscope.  There is a discussion in that article of the Volta/Galvani dispute, and that might be a better place to link to galvanism. SpinningSpark 13:08, 19 May 2020 (UTC)
