MagNet 2D/3D Electromagneic Field Simulation Software

With our easy to use and accurate software, you can virtually prototype simple to complex electromagnetic and electromechanical devices.

MagNet 2D/3D is a powerful simulation software which engineers and scientists worldwide use for the design of motors, sensors, transformers, actuators, solenoids or any component with permanent magnets or coils.

Be more efficient. Virtual prototyping can save both time and money. Multiple configurations can be explored quickly, providing insight into performance for design improvements which reduce costs.


Accurately modeling

The model presented here is the simulated results of the ohmic losses and flux density of a 3 phase transformer with a three limbed paramagnetic core.


MagNet offers both 2D and 3D electromagnetic field simulations, all within the same user friendly interface:

  • Magnetostatic
  • Frequency dependent (AC)
  • Time varying, including the effects of moving components

They can be linked to ThermNet for coupled thermal-electromagnetic field simulations.

Recent Improvements

  • New coil definition tool which detects current path and direction
  • Significant speed up due to new algorithm for Newton convergence
  • Algorithmic parallelism improvements in all 2D and 3D solvers
  • Improved nonlinear surface impedance approximation
  • Easily model laminations with the perfect electric insulators boundary condition
  • Predict the surface force density on a component
  • Multicore mesh generator, solvers and post-processor for even faster results

MagNet uses the finite element technique for an accurate and quick solution of Maxwell's equations. Each module is tailored to simulate different types of electromagnetic fields and is available separately for both 2D & 3D designs.
