Strongest magnetic field in a superconductor
Please re-Explain the Explanation to provide a deeper conceptual image of this pseudo-scientific and impractical sounding phenomenon, and cite some sources!
"in the magnetic field of a huge horseshoe magnet 0,001 T,"
Hello, is this a typo? Can someone more experienced than I answer?
This value 0f 0.001T is pretty low for a "huge" horseshoe magnet. Old fashioned magnets could create field of > 100 gauss, or 0.01T. More modern permanent rare-earth magnets have fields more like 10,000 gauss or about 1 Tesla.
The definition shouldn't use the shorthand symbols only; it should have the definition in terms of the names of the units as well, to avoid confusion. --Starwed 20:15, 10 February 2006 (UTC)
- And shouldn't the dashes in the various units (like m-2) be the same length? They vary... ~Gertlex 18:02, 23 July 2006 (UTC)
hey.. someone put this in terms someone not taking physics would understand. like.. the amount of 1gram paperclips a magnet could pick up at 1 tesla.
- Your example would be measured in webers, not teslas. For tesla examples, see the list of examples in this article. --Heron 21:12, 6 April 2006 (UTC)

Defining all these combinations of the SI units adds nothing to article

Makes no sense - what is being "reduced"? How does this have any relation to the definition of a unit?

Shouldn't n, the number of turns, be included when V or A are involved in the definition? Voltage should be volts/turn and current should be Ampere-Turns —Preceding unsigned comment added by 18.104.22.168 (talk) 00:23, 20 January 2010 (UTC)

How many tesla is a maglev track? Or a magnetic induction rail for transportation?
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 22.214.171.124 (talk) 14:45, 22 March 2010 (UTC)
- 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.
"Electric vs Magnetic Field" what is this?
"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)."
Units are WRONG!
The SI base units for the tesla is wrong in the Wiki article. Consult WolframAlpha and other sources. — Preceding unsigned comment added by 126.96.36.199 (talk • contribs) 03:40, 21 September 2011 (UTC)
- Huh? We can ignore this one. —Quondum 06:54, 19 February 2014 (UTC)
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..."
- Agreed. Done. —Quondum 06:43, 19 February 2014 (UTC)

Conflict of unit (T) with prefix (T)
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)
