WebFeb 28, 2013 · The curl of a gradient is always zero. No matter what the domain of the vector field is. The "converse" is not generally true. That is: if the curl of a vector field is 0, then it is the gradient of something. That requires the domain to be simply connected. This last statement is essentially the Poincaré lemma. WebFeb 23, 2024 · The gradient of a scalar field points into the direction of the strongest change of the field. So it is perpendicular to isosurfaces of the scalar field and that already requires that the curl of the gradient field is zero. A good example to visualize is a temperature distribution.
