Modules

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.

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.


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.

Transient (Time-varying)
