Guided input for round, rectangular and triangular ring cores with simple and advanced modes.
Automatic dependencies between dimensions – fewer mistakes than manual calculation.
Optional housing with its own material model and gap dimensions.
Export as a STEP file and a two-page DIN A4 drawing (construction + simulation curves); the FCStd source file is additionally available to internal users.
Design library
Versioned designs with filters, detail views, duplication, reuse and project linkage.
Every change is saved as a new version – nothing is lost, nothing is overwritten.
Duplicate existing designs and use them as a starting point for new variants.
Direct assignment to simulation projects for traceable comparisons.
Simulation projects
AL and impedance curve comparisons based on pinned design versions for reproducible decisions.
Structured material and permeability database as the calculation basis.
Tolerance points at the relevant frequencies (AL at 10 kHz/100 kHz, |Z| at 600 kHz/2 MHz/60 MHz).
Multiple design versions pinned and compared directly instead of assembling files manually.
Winding Design Beta
Plan turn count, wire and fill factor directly on the core and check live whether the winding fits mechanically.
Hexagonal-lattice packing model for the winding window and outer diameter, numerically verified.
Admin-maintained wire library (enamelled copper wire per IEC 60317) with a custom-entry option.
Beta feature developed in short cycles - calculation and display may change.
Register for free, daily and design limits included – no payment required for everyday, productive use.
MagSim is a private, self-funded project. Usage limits such as the number of saved designs or generations per day exist solely to keep the operator's running costs under control – not to monetize usage.
MagSim in action
Two short, silent image sequences instead of an explainer video: how a design goes from the form to the download – and how two equally sized cores with different core material diverge on the chart.
Generate and download a design – including a look inside the real PDF drawingMaterial comparison: same core size, Nanocrystalline µr 30k versus Ferrite µr 10k
In-depth guides
Background on the topics behind the generator – readable independently, no registration required.
