The design of gradient coils is sometimes perceived as complex. However, the relation between a current density and a stream function is a simple differentiation. Here we present an intuitive open source code collection to derive gradient coil designs from current densities. Stream functions are derived directly and indirectly from the current distribution. The aim of this work is to provide a simple tool for educational purposes. The code collection which is available on GitHub enables for straight-forward coil designs on simple surface geometries.
