Curl theorem
WebThe same equation written using this notation is ⇀ ∇ × E = − 1 c∂B ∂t The shortest way to write (and easiest way to remember) gradient, divergence and curl uses the symbol “ ⇀ ∇ ” which is a differential operator like ∂ ∂x. It is defined by ⇀ ∇ = ^ ıı ∂ ∂x + ^ ȷȷ ∂ ∂y + ˆk ∂ ∂z and is called “del” or “nabla”. Here are the definitions. WebStokes theorem says that ∫F·dr = ∬curl (F)·n ds. If you think about fluid in 3D space, it could be swirling in any direction, the curl (F) is a vector that points in the direction of the AXIS OF ROTATION of the swirling fluid. curl (F)·n picks out the curl who's axis of rotation is normal/perpendicular to the surface.
