Top 10 Best Magnet Simulation Software of 2026

COMSOL Multiphysics covers magnetostatic analysis with vector field outputs, boundary conditions, and material definitions that include demagnetization-relevant permanent magnet modeling. It also supports transient electromagnetic modeling with eddy current effects and time integration choices that affect stability and runtime. A single geometry and mesh setup can be reused across variants using parametric definitions, which helps labs standardize a study protocol across antenna, EMI, and actuator magnet designs.

A practical tradeoff is model complexity, since high-fidelity magnet studies often require careful meshing near small gaps and detailed material data entry for hysteresis-like behavior using available nonlinear options. COMSOL fits best when teams need repeatable parametric studies plus extraction of magnetic flux density metrics, stray field regions, and force or torque from the same physics model rather than exchanging outputs between separate tools.

JMAG’s magnetics workflow is organized around FEM modeling of magnetic components with nonlinear material curves such as B-H data, which is directly relevant for predicting flux density, stray field, and saturation behavior. For EMI and dynamic electromagnetic tasks, it provides transient electromagnetic and eddy-current modeling so designers can evaluate time-dependent currents, induced effects, and heating-relevant field behavior. The post-processing stack focuses on engineering outputs such as field maps, force and torque extraction, and derived metrics used to compare candidates during optimization.

A practical tradeoff is that accuracy and throughput depend on mesh quality and nonlinear convergence settings, which can require model tuning when switching between magnetics and transient electromagnetic studies. JMAG fits best when a lab or engineering team needs one environment to run repeated simulations across antenna or magnetic hardware variants, then extract comparable force, torque, and field homogeneity metrics for design review.

Field Precision is positioned for magnet and electromagnetic field work where geometry realism drives results. It supports magnetostatic analysis with outputs that engineers can use for flux density maps, field homogeneity comparisons, and stray field visibility around components. The workflow emphasizes re-running the same study with controlled changes, which helps teams converge on a design faster than manual setup each time.

A practical tradeoff is that complex coupled electromagnetic scenarios are less direct than in tools that focus first on transient electromagnetic solver workflows. Field Precision fits best when studies are dominated by geometry-driven magnetostatic behavior and when teams need consistent re-parameterization across antenna or permanent magnet array variants.

QuickField is magnet simulation software focused on making field and force workflows practical for engineers working on antenna, EMI, and magnetic studies. It provides a finite-element modeling workflow with material definitions and problem setup tools aimed at repeatable studies across geometries and boundary conditions.

QuickField also supports multiphysics-style coupling for electromagnetic effects and includes postprocessing steps for magnetic flux density visualization and force evaluation on selected objects. For teams that need iteration and parameter changes, QuickField’s scripting and automation options help turn one-off models into repeatable analysis runs.

FEMM performs 2D finite element magnetostatic analysis with optional eddy current modeling in a workflow centered on problem geometry, materials, and boundary conditions. It distinguishes itself by being open-source and scriptable through an interpreter-driven model builder and solver loop.

Models use built-in support for nonlinear material behavior with B-H curves to capture saturation effects in ferromagnetic parts. Output includes field quantities suitable for force and torque calculations on selected contours and regions.

Elmer FEM is an open-source finite element method suite used for magnetostatic analysis and related electromagnetic workflows, including eddy-current modeling. It couples nonlinear material behavior for ferromagnetic saturation with custom physics via its equation-based solver stack.

The project also provides a strong path for parametric sweeps because the solver is scriptable and mesh-driven through Elmer’s control files. Elmer FEM is distinct from many CAD-first magnet tools because it treats magnetics as a set of configurable PDEs and solver components rather than a fixed GUI workflow.

EMWorks targets antenna, EMI, and magnetics workflows with a simulation chain focused on field computation and engineering outputs rather than generic multiphysics authoring. It supports parametric models for magnetic structures and field regions so teams can iterate on geometry and operating conditions while keeping results tied to magnet-relevant quantities.

The workflow emphasizes repeatable runs, result extraction, and project-level consistency across studies. Integration and automation are handled through EMWorks’ scripting and data exchange options so external processes can drive sweeps and postprocessing.

Extende CIVA is a CIVA-based workflow for magnetostatic and related electromagnetic tasks that centers on prebuilt geometry, material assignment, and analysis automation. The toolchain is geared for antenna and magnetic study pipelines where repeated parameter sets and consistent solver setup reduce manual effort.

CIVA’s modeling workflow supports study-to-study reuse through saved configurations, which helps teams standardize boundary conditions, excitation settings, and postprocessing outputs. Extende’s integration into engineer-facing simulation processes makes it easier to run batch analyses and compare results across design iterations.

Onelab runs magnet simulation workflows with a configurable, script-driven toolchain aimed at antenna and magnetostatic use cases. It focuses on coupling magnetic geometry definition, solver runs, and post-processing into repeatable tasks that labs can rerun with controlled settings.

The software also supports parameterized study patterns so experiments can be reproduced across geometry variants. Output analysis is organized around field quantities needed for antenna-related magnetic flux density, stray field, and force or torque style computations.

Pyleecan targets magnet simulation workflows with an emphasis on parametric geometry and repeatable field computation runs. The tool focuses on magnetic field and force workflows for common antenna and EMI-oriented investigation tasks like stray field behavior and interaction checks.

It supports iterative design loops where inputs change and results must be regenerated without manual, ad hoc steps. Automation and repeatability matter most for teams that run many closely related magnet configurations.
