Magnetic simulation software enables engineers to model magnetic fields, predict flux density, analyze force and torque, and optimize magnetic circuit designs before committing to physical prototypes. Finite element analysis (FEA) tools are the industry standard for this work, allowing designers to evaluate how changes in magnet grade, geometry, air gap, and surrounding materials affect system performance. Simulation is used across electric motor design, sensor development, magnetic shielding, MRI system engineering, and magnetic actuator development.

What to Look for in Magnet Simulation Software

• Solver capability — Confirm the software supports the physics relevant to your application — magnetostatics, time-harmonic analysis, transient simulation, or coupled electromagnetic-thermal analysis. Not all tools handle all solver types with equal accuracy.
• Geometry and CAD integration — Leading tools support direct import of CAD geometry from common formats including STEP and IGES, reducing the time spent rebuilding models from scratch in the simulation environment.
• Material libraries — Comprehensive magnet material libraries with accurate BH curve data for common NdFeB, SmCo, ferrite, and alnico grades are essential for accurate simulation results. Confirm the library covers the materials relevant to your work.
• Motor and drive coupling — For electric motor development, look for tools that support coupling between electromagnetic simulation and motor drive circuit modeling, enabling system-level performance prediction.
• Support and training — Simulation software has a significant learning curve. Evaluate the quality of documentation, training resources, application engineering support, and active user communities before committing to a platform.
