Curl of a scalar times a vector
WebYes, curl indeed is a vector. In the x,y plane, the curl is a vector in the z direction. When you think of curl, think of the right hand rule. It should remind you of angular momentum, who's vector direction is in the direction perpendicular to the plane of rotation.

Web2 days ago · 2 The 0-th component of the vector eld is xed due to the unit-timelike constraint while its spatial part is given in general as a gradient of a scalar mode and the curl of a spatial vector. In this study, we ignore the curl mode since it vanishes in spherical sym-metry. MNRAS 000, 1{15 (2024) WebMar 29, 2024 · The curl is a vector operator that describes the infinitesimal rotation of a vector field in three-dimensional space. The curl of a scalar field is undefined. It is …

WebWith f a vector function of the coordinates, ∇ × f is a vector called the curl of f. These three symbols ( ∇, ∇., ∇ ×) are differential operators and represent no quantity by themselves. If you really want to see ∇ as a vector, then it is. ∇ = i ∂ ∂ x + j ∂ ∂ y + k ∂ ∂ z. Share.
WebTechnically, curl should be a vector quantity, but the vectorial aspect of curl only starts to matter in 3 dimensions, so when you're just looking at 2d-curl, the scalar quantity that you're mentioning is really the magnitude of …
The curl of the gradient of any continuously twice-differentiable scalar field (i.e., differentiability class ) is always the zero vector : It can be easily proved by expressing in a Cartesian coordinate system with Schwarz's theorem (also called Clairaut's theorem on equality of mixed partials).
