Walkthroughs grouped by experience level. Each tutorial produces a real, exportable result — PDF, KiCad, DXF or SPICE — that you can build on.
Pick the circular Helmholtz topology, set geometry, run, and read the coupling factor.
Turn radius, spacing, wire count — what each input does and how it shifts the field.
Use the genetic optimiser to hit a target k with bounded geometry.
Batch over a parameter range and export the full result set.
Cross-check AirInduct output against Babic & Akyel and Kurs et al. on a reference coil.
Air gap, misalignment tolerance, ferrite placement — full SAE J2954 walkthrough.
