WebMar 10, 2024 · 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. [1] 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.
