I think where I'm getting confused is this. Take your square path and place the paddlewheel along any segment of it and it should turn if the path falls say on the left paddle and not the right. Since it's a line segment it can't fall on both. Or are talking about the field of vectors inside an...

So would that not apply to everything leading to a zero curl for any equation? You didn't use your first equation to make your point.

Born2Bwired: You're equation above is a vector in the x y plane. I don't see why this equation, if plotted, and if the line of the graph were a flow of water, could not turn a paddlewheel whose axis were in the z plane? The only time a plotted equation in the x y plane whose graph is a flow...

So what you're saying is that B does not cause the vectors of E to curl? Or, if you think about it, maybe the intersection of two E fields which bends the lines of flux, is the curl you're talking about.

So here's a fundamental question that has been building up for me and only now do I have the chance to ask. If you take the electric field of a single point charge which radiates outward in ever grown spheres at the speed of light until stabilizing into a steady state...this is an irrotational...

So the equation states... the curl of E equals the rate of change of B?

Woops. Don't you mean Nabla X E? That's the eq Nabla X E = pdB/pdt So is Nabla X E the measure of the tendency of a vector field at a specific point to run in loops around the point? It must be, based on your Nabla X B answer. :) And what in reality causes a point in an electric field to run...

Thanks, I know the site. It's good. The eq Nabla cp E = part deriv B / part deriv t The right hand side is the rate of change of B wrt to t. Right? What does the left hand side mean in similar language? I would guess something like the rate of change of E in x hat, y hat and z hat but I'd...

Brilliant! Thank you for taking the time to present that well-thought out answer to my question. It was enlightening, for sure. But as to the nature of truth, I think Descarte said it best. "I think, therefore I am." This we can know for sure. Whether you guys are really out there or not cannot...

I'm not a big fan of plastics but I love LaTeX. So this forum's message boxes are LaTeX friendly. How can you tell if other text editors are as well? Is there a standalone editor you can have on your personal computer that allows this scripting? Maybe there's a LaTeX forum, sorry if this is in...

\nabla \cdot \mathbf{E} = \frac{\rho}{\epsilon_0}

Hey, to get the pretty mathematical symbols do you use a scripting language, keyboard shortcuts or a software you have to download? What is it and and do I do it? Dunka

I get it! Thanks.

Spherical coordinates are very important Yet I could define a sphere easily in (I guess what you call R^3 space, x,y,z coordinates. I guess it would be more difficult though now that I think about it.

Thanks. Can you reference an actual problem so I can see how it's done. On the web possibly? Or a textbook?
