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 … See more The curl of a vector field F, denoted by curl F, or $${\displaystyle \nabla \times \mathbf {F} }$$, or rot F, is an operator that maps C functions in R to C functions in R , and in particular, it maps continuously differentiable … See more Example 1 The vector field $${\displaystyle \mathbf {F} (x,y,z)=y{\boldsymbol {\hat {\imath }}}-x{\boldsymbol {\hat {\jmath }}}}$$ can be decomposed as See more The vector calculus operations of grad, curl, and div are most easily generalized in the context of differential forms, which involves a number of steps. In short, they correspond to the derivatives of 0-forms, 1-forms, and 2-forms, respectively. The geometric … See more • Helmholtz decomposition • Del in cylindrical and spherical coordinates • Vorticity See more In practice, the two coordinate-free definitions described above are rarely used because in virtually all cases, the curl operator can be applied using some set of curvilinear coordinates, for which simpler representations have been derived. The notation ∇ × F … See more In general curvilinear coordinates (not only in Cartesian coordinates), the curl of a cross product of vector fields v and F can be shown to be See more In the case where the divergence of a vector field V is zero, a vector field W exists such that V = curl(W). This is why the magnetic field, characterized by zero divergence, can be expressed as the curl of a magnetic vector potential. If W is a vector field … See more Webcurl, In mathematics, a differential operator that can be applied to a vector -valued function (or vector field) in order to measure its degree of local spinning.
