message: Commercial superconducting NMR magnets reach 20T. Furthermore, the link in ref. [2] is broken. So this passage should be deleted or corrected. 132.230.182.55 (talk) 13:06, 7 May 2015 (UTC)
thread_title: Strongest magnetic field in a superconductor

message: The definition should be kg/C•s rather than kg/A•s². Amps are a derivative measurement from Coulombs and seconds which are the fundamental measurements involved. Given that it is given in several different forms, leaving kg/A•s² makes sense, but the SI base units should be corrected to use Coulombs rather than Amperes. 
: "SI base units should be corrected to use Coulombs rather than Amperes" - OK, so talk to CGPM and try persuading them. Meantime, your edits are undone.Evgeny (talk) 08:12, 8 June 2023 (UTC)

message: The page says he's "Yugoslavian-American", but Tesla's own Wiki article says he was born in Austria, which is definitely not Yugoslavia. Yugoslavia is a part of Europe, which is stated on the Yugoslavia article. And before anyone complains to me about it, no, I won't edit it myself, because every edit I make is always reverted on Wikipedia, whether I'm trolling or not.  —Preceding unsigned comment added by 74.195.230.26 (talk) 14:45, 22 March 2010 (UTC)
replies: text: care to do some more homework before typing in here? Yugoslavia- does not exist anymore. And yes parts of former Yugoslavia were also part of Austrian-Hungarian Empire. Care to learn more about history? So all statements are correct: he is Serbian first and foremost.That is his nationality.But he could be considered Austrian and Yugoslavian as well.. Glad to be of help.

message: "Electric vs Magnetic Field
It's sometimes confusing as to the difference between magnetic field (in tesla) vs electric field strength.
The difference is that a magnetic field is moving while an electric field isn't, this can be seen by looking at the units for each. Electric field is N/C, while magnetic field (in tesla) can be written as N/(C*m/s). Showing the difference between the 2 clearly is m/s, or movement.
In ferromagnets the movement creating the magnetic field is the electron spin (and to a lesser extent electron orbital angular momentum). In current carrying wire (electromagnets) the movement the electrons move through the wire (whether the wire's straight or circular)."
Please remove this. It's badly written and barely makes any sense. Does anybody agree? --79.55.31.10 (talk) 14:12, 31 March 2011 (UTC)

thread_title:  Units are WRONG! 

message: The bulk of the Conversions section consists of unsourced claims about the unit's non-usage among engineers, (although several of the article's sources seem to indicate otherwise), and claims that publications that do use it (presumably including mainstream journals) 'often' capitalize the unit. The correction is then oddly worded:
:"However, as with gauss and other units, even those derived from names (watt, joule) the unit is lower-case when written out..."
...seeing as the allegedly preferred gauss is also derived from a name. The paragraph should probably be removed per WP:NOR. AveVeritas (talk) 06:10, 19 February 2014 (UTC)

thread_title:  External links modified 

message: Shouldn't there be a section describing the problem with this SI derived unit?  All other official SI units (to my knowledge) are carefully designed to avoid conflict and ambiguity.  But the tesla (unit) is given the symbol T, which is in direct conflict with the Terra (prefix) also a capital letter T.
For example, if one were to read 2.5 Tm, should that be interpreted as 2.5e+12 meters (a distance), or as 2.5 tesla*meters (a magnetic potential).
I read on the page about torque (as I recall) that the SI recommends, for example, Nm (newton-meter) to be used for torque, instead of mN (which is ambiguous -- it could mean meter-newton or milli-newton).  But there is no discussion about the ambiguity with the symbol for tesla units -- which is a more serious problem in my opinion.  I've been looking around for more info, and if I find it, I will update the article.  Until then, any comments? Hydradix (talk) 01:38, 23 August 2016 (UTC)
