Magneto Static solution

Solutions > Electromagnetics > Magneto Static

Introduction

The Magneto Static application allows the user to study the phenomena created by a magnetostatic field. The magnetic field is related to the presence of DC currents (stationary currents) and/or of permanent magnets.

Note: For more information about the Magneto Static workflow, please consult:

Use

The Magneto Static application can be used to model different devices.

Thus, we can compute:

  • he magnetic field in the structures with magnets for particle accelerators, spectrometers or MRI magnets, attenuation of the magnetic field due to the magnetic shieldings, the field of magnetic reading heads
  • the forces in magnetic bearings, in the electromagnets and in the contactors
  • the torques in rotating machines and micromotors
  • the self-inductance and mutual inductances of different devices (transformers, coil-ends of rotating machines...)

Solution dialog box

  • The magnetostatic solution is available for 2D, 3D and Axisymmetric cases.
  • In case of 2D the domain depth must be defined to take into account the electromagnetic effects in the third dimension.
  • In Magneto Static 3D containing Motion load, once the Motion load is created, the solution dialog box is updated with new inputs: the Motion parameters to pilot the position of the moving bodies during the solving:

    Monovalue allows to solve with the entered position. Multivalues allow to solve with the position varying from a Lower limit to a Higher limit with a Step value. For more information on the Motion, please refer to MS3D Motion
