Talk:Magnetic flux

message: :I added the reference to Maxwell's equations because of that, but it is still unsatisfying.  Lemme see how it can be reworded. --Laura Scudder 23:32, 9 Apr 2005 (UTC)
replies: text: I just removed the reference to the vector potential since it has no direct connection to discussion. --Laura Scudder 23:43, 9 Apr 2005 (UTC)

message: The article states that:
:Magnetic flux density, otherwise known as magnetic field density, is essentially what the layman knows as a magnetic field
It's also what pretty much every physicist knows as the magnetic field, and authors like Jackson and Griffith concur on such usage.  So I think "the layman" here is a bit misleading.  --Starwed 13:08, 27 February 2007 (UTC)
thread_title:  "Layman" 

message: I have thought for a while that the electromagnetism template is too long.  I feel it gives a better overview of the subject if all of the main topics can be seen together.  I created a new template and gave an explanation on the old (i.e. current) template talk page, however I don't think many people are watching that page.
I have modified this article to demonstrate the new template and I would appreciate people's thoughts on it: constructive criticism, arguments for or against the change, suggestions for different layouts, etc.
To see an example of a similar template style, check out Template:Thermodynamic_equations.  This example expands the sublist associated with the main topic article currently being viewed, then has a separate template for each main topic once you are viewing articles within that topic.  My personal preference (at least for electromagnetism) would be to remain with just one template and expand the main topic sublist for all articles associated with that topic.--DJIndica 16:45, 6 November 2007 (UTC)

Can someone re-word this? --Treekids (talk) 18:38, 12 June 2008 (UTC)
thread_title: gibberish

message: What is the definition of flux through a coil doing there? Its nothing more than applying the general definiton of magnetic flux (in fact the equation is a repeat of the definition - and once again the dot for the dot product is missing). The section is too short anyway, hence its redundant. The section makes it appear that the flux through a coil has a seperate/special case definition. 
On the other hand - the video is certainly good to include. 
Given these issues - I deleted everything in the section except the video and a sentence related to the video.
If there is any favour to restore the section and extend it to some volume - please do. F = q(E+v×B) ⇄ ∑ici 13:59, 25 March 2012 (UTC)

message: I also tried to tidy the positioning of the images - if according to your browser the images still are cluttered: tweak as neccersary. F = q(E+v×B) ⇄ ∑ici 14:01, 25 March 2012 (UTC)

message: The text states "(see below for deciding in which direction the field lines carry a positive sign and in which they carry a negative sign).", but there is no further mention of this.

thread_title:  Sign of Field Lines 

message: The equation for magnetic flux on the page says that Φ = B⋅S = BS sin θ. I don't know what the literature says on the subject, but this equation is mathematically wrong. The dot product of the two vectors B⋅S is BS cos θ. For it to be BS sin θ, you'd need to be talking about the magnitude of the vector B×S or the magnitude of the bivector B∧S. 2603:6080:CC00:193:C9E2:11BE:C088:7008 (talk) 20:03, 4 August 2023 (UTC)
