Setting skin of Wire to be non-conducting in Magnetostatic simulation

    • nc378690
      I am trying to find the torque on a permanent magnet from a solenoid. I have the solenoid modelled but I need to pass current through the coils, which I am not sure how to do correctly since the solver tries to make the current go through the copper material as if it was all conducting. How do you set the skin of the wire to have an infinite resistance, to mimic the presence of the enamel that is there in real life?

      I think this is a very practical application of this simulation so I am sure some one has encountered it before.

      Hi @nc378690,

      What is important here is the Ampere turns and the mmf generated by the coil. So, when you define the coil as a solid(which is enough for your application) applied current is equally distributed throughout the coil. When you define the current it is actually the ampere turns value.

      If the coil is touching any of the conducting objects, you can assign an insulation boundary condition to the outer surface of the coil.

      1) you can refer to the inbuilt example in this path - File>openexamples>Maxwell>General>Magnetostatic>Ex_MS_1_Magnetic_Force

      2)You can go through the below getting started guide

      3) You can also refer to the below video in the Ansys innovation courses
