In three dimensions, the rotation of a vector field $\vec{F}(\vec{r}) = (F_x, F_y, F_z)$ is defined as: $rot \vec{F}(x, y, z) = \nabla \times \vec{F}(x, y, z) = \left(\frac{\partial F_z}{\partial y} - \frac{\partial F_y}{\partial z}\right)\hat{e}_x + \left(\frac{\partial F_x}{\partial z} - \frac{\partial F_z}{\partial x}\right)\hat{e}_y + \left(\frac{\partial F_y}{\partial x} - \frac{\partial F_x}{\partial y}\right)\hat{e}_z$ Exercise: Calculate the rotation and sketch the following vector field: $\vec{v}(\vec{r}) = \begin{pmatrix} by \\ 0 \\ 0 \end{pmatrix}$
