WebThe magnitude of the curl vector at P measures how quickly the particles rotate around this axis. In other words, the curl at a point is a measure of the vector field’s “spin” at that point. Visually, imagine placing a paddlewheel into a fluid at P, with the axis of the paddlewheel aligned with the curl vector (Figure 6.54). The curl ... Webcurl (fF) with Einstein Summation Notation. I considered the k th component of curl f F. f is a scalar field and F a vector field. Hereafter, I refer only to the term with the star underneath. Since [ F j corresponding to F] appears before [ ∂ i f corresponding to ∇ f ], thus ϵ i j k F j ∂ i f = [ F × ∇ f] k.
