Short paths to a working design.
Walkthroughs grouped by experience level. Each tutorial produces a real, exportable result — PDF, KiCad, DXF or SPICE — that you can build on.
Curriculum
Beginner5 min
Your first Biot–Savart simulation
Pick the circular Helmholtz topology, set geometry, run, and read the coupling factor.
Beginner8 min
Understanding the 13 parameters
Turn radius, spacing, wire count — what each input does and how it shifts the field.
Intermediate12 min
Optimising for target coupling
Use the genetic optimiser to hit a target k with bounded geometry.
Intermediate10 min
Parameter sweeps end-to-end
Batch over a parameter range and export the full result set.
Advanced15 min
Checking against closed-form references
Cross-check AirInduct output against the Grover and Babic & Akyel closed forms on a reference coil.
Advanced18 min
Designing for EV inductive charging
Air gap, misalignment tolerance and when to hand ferrite and shielding to FEM — an SAE J2954 walkthrough.
