A solver that stands up to peer review.
AirInduct has no mesh approximations and no fitted models. Results are checked against published reference cases, listed on the validation page.
How do researchers use AirInduct Sim?
Researchers use AirInduct Sim to generate reproducible coupling and inductance data for inductive wireless power transfer without building a FEM model. Identical inputs return identical outputs on every run, and results can be checked against published reference cases. A typical study fixes a coil pair, sweeps one parameter such as air gap or lateral offset, plots M and k against it, and exports the figures in a PDF report alongside a SPICE netlist for the circuit side. Students can compare all eight topologies, from Helmholtz pairs to DTC planar spirals, in one session. The model is air-core and magnetostatic, so studies of ferrite, shielding or radiation need a FEM or full-wave tool. Batch studies can also be scripted through the AirInduct Sim MCP server.

Frequently asked questions
Is AirInduct Sim suitable for academic WPT research and publication?
Yes. AirInduct has no mesh approximations and no fitted surrogate models, results are checked against published reference cases, and identical inputs always return identical outputs.
Can I cite AirInduct Sim in a paper?
Yes. Suggested citation: "AirInduct Sim — Browser-based WPT coil simulator with magnetic field solver and mutual-inductance calculation. https://airinductsim.com (accessed 2026)."
Can I run batch experiments programmatically?
Yes, through the AirInduct Sim MCP (Model Context Protocol) server at https://api.airinductsim.com/mcp/. With an API key it exposes the same tools as the in-app Copilot — single runs, gap and misalignment sweeps, design comparisons and link analysis — for agent-driven or scripted experiments.
How does AirInduct compare to FEM EM simulators for academic use?
For air-core inductive WPT in the magnetostatic regime, AirInduct needs no mesh, so it is fast and reproducible. FEM remains the right tool for ferrite, shielding and eddy currents. We do not publish a head-to-head percentage against those packages.
