[edit] Alternate form of Ampere's Law

Why is there no mention of \oint_{l} \vec B\cdot d\vec l=\mu_0I on this page? --70.81.118.123 06:23, 5 December 2005 (UTC)

Was here,but someone must have deleted it.--85.103.37.24 10:16, 19 January 2006 (UTC)

I put it back, they're integrated now. This page needs *work* and the terminolgy is all messed up. Particularly confusing is the difference between B and H. Not to mention that H is magnetic field density on the Maxwell's equations page, and magnetic flux density on this page.. I'm too confused to fix more. Fresheneesz 22:51, 3 February 2006 (UTC)

H is not magnetic flux density.....B is magnetic flux density..H is magnetic flux intensity..similar what electric field is in electrostatics...[vijin]

[edit] whats dA

What's da in the first formula?

I'd vote for an infintesimal part of the surface S. This is a surface itself. In French, the word "aire" is used for surface. I suggest to change da for ds.

I added the defintion from the page Maxwell's equations. This page needs to define ALL its variables - its in poor shape. Fresheneesz 22:59, 3 February 2006 (UTC)
