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. WebJan 17, 2015 · For any 1-form A , ( ⋆ d)( ⋆ d)A = ( ⋆ d ⋆)dA curlcurlA = d † dA Recalling that Δ = dd † + d † d, we see that curlcurlA = − dd † A + ΔA = d( ⋆ d ⋆)A + ΔA = …

WebMar 10, 2024 · The curl is a form of differentiation for vector fields. The corresponding form of the fundamental theorem of calculus is Stokes' theorem, which relates the surface integral of the curl of a vector field to the line integral of the vector field around the boundary curve. Curl F is a notation common today to the United States and Americas. WebThe Curl The curl of a vector function is the vector product of the del operator with a vector function: where i,j,k are unit vectors in the x, y, z directions. It can also be expressed in determinant form: Curl in cylindrical and sphericalcoordinate systems.
