WebFeb 26, 2024 · ∇ ⋅ ( ∇ × F) = 0 , and this implies that if ∇ ⋅ G = 0 for some vector field G, then G can be written as the curl of another vector field like, G = ∇ × F. But this is one of the solutions. G can also be written as G = ∇ × G + ∇ f where ∇ 2 f = 0 and ∇ ⋅ F = 0. I'm confused about this as well. 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.
