Fast, simplified
coil simulation.
No geometry. No meshing. No ports. Enter the parameters and get mutual inductance, coupling factor and full H-field grids — in seconds.
Make coil design accessible to every engineer.
We built AirInduct to close the gap between theoretical EM simulation and practical coil engineering. No expensive licences, no black-box solvers — fast, validated Biot–Savart results anyone can inspect and trust.
A simulation engine from first principles.
The solver computes magnetic fields using Biot–Savart with Neumann mutual-inductance and complete-elliptic-integral kernels — no finite-element approximations. Eight coil topologies, three render modes, exports to KiCad, DXF and SPICE.
Where wireless power is headed.
A future where AI-driven optimisation and real-time simulation replace manual parameter sweeps. From concept to production-ready coil — designed, validated and exported in minutes, not weeks.
Trusted platform for coil design.
Set coil geometry, run a Biot–Savart simulation, and get mutual inductance, coupling factor, and full H-field grids — in seconds. Export to PDF, KiCad, DXF or SPICE and ship your design.
One engine. Three surfaces.
The same Biot–Savart core ships across mobile, web and desktop — so the result you read in the lab matches the one your colleague sees on the train.
On the move.
Same engine, presets and history — sized for your pocket.
