In vector calculus, the curl is a vector operator that describes the infinitesimal circulation of a vector field in three-dimensional Euclidean space. The curl at a point in the field is represented by a vector whose length and direction denote the magnitude and axis of the maximum circulation. The curl of a field is formally defined as the circulation density at each point of the field.

Web(The curl of a vector field doesn't literally look like the "circulations", this is a heuristic depiction.) By the Kelvin–Stokes theorem we can rewrite the line integrals of the fields around the closed boundary curve ∂Σ to an integral of the "circulation of the fields" (i.e. their curls ) over a surface it bounds, i.e. WebIndex notation is used to represent vector (and tensor) quantities in terms of their constitutive scalar components. For example, a i is the ith com-ponent of the vector ~a. Thus, a i is actually a collection of three scalar quantities that collectively represent a … WebApr 22, 2024 · From Curl Operator on Vector Space is Cross Product of Del Operator and Divergence Operator on Vector Space is Dot Product of Del Operator : where ∇ denotes the del operator . where r = (x, y, z) is the position vector of an arbitrary point in R .
