Solenoidal vector field

4.6: Gradient, Divergence, Curl, and Laplacian. In this final section we will establish some relationships between the gradient, divergence and curl, and we will also introduce a new quantity called the Laplacian. We will then show how to write these quantities in cylindrical and spherical coordinates.
