WebOct 20, 2015 · To conclude, your formula for the curl should be right. Just be careful to use the right normalisations for the vectors and you should be fine (also be careful of the tensorial form of the levi-civita tensor, which involves the determinant of the metric). Web\] Since the \(x\)- and \(y\)-coordinates are both \(0\), the curl of a two-dimensional vector field always points in the \(z\)-direction. We can think of it as a scalar, then, measuring how much the vector field rotates around a point. Suppose we have a two-dimensional vector field representing the flow of water on the surface of a lake.
