In the Workflow, press the Physics button. Right click on the enclosure and select Hide Body.
Next to Material Assignments, press the Add drop down menu Material Assignment > Search for Cast Iron (Material Samples) and select it. Make sure you change the Isotropic relative permeability to 1(10)^5. Next, click on the Body Selection tool in top right corner and select the three beams and click Add.
Next, a magnetic material will be created. Instead of searching for cast iron, search “Mag” and click on Create Mag. Set the Default State to Solid. To create a material property, select Add and choose the following material properties. Input 625000 S m^-1 for Isotropic Electrical Conductivity. Input 5.305 for Isotropic Relative Permeability. Input 150000 A m^-1 for the Magnetic Coercivity. (You can use “Type to Search” to find the Magnetic Coercivity property.) Select Cartesian magnetization direction, then input 3/2 for the X direction (you can enter the expression sqrt(3)/2 to define the x direction) and 1/2 for the Y direction.
