Analytical and numerical calculation of the magnetic field generated by a modulated double helical coil (double helix coil, canted-cosine-theta coil). The analytical solution is obtained from [1, Eq.(13)]. The numerical solution is obtained by numerical integration of the Biot-Savart’s law in the filament approximation (require BSmag toolbox).
