Then click on next step and repeat the process, assigning Steel 1010 (Material Assignment) to the yoke and center pole by control selecting both and click on the "+". (You can use “Type to Search” to find Steel 1010 in the material library.)
In order to see the B-H curve of Steel 1010, click on the arrow next to the blue lettered Steel 1010. Then click on the chart symbol for the B-H Curve. Below is the nonlinear B-H for Steel 1010.The chart below shows that the yoke and center pole are made out of a saturable material. This means as we increase the current the Steel 1010 will saturate, which results in the inability of the Steel 1010 material to carry any more magnetic flux. Click on the x in the top right corner when finished viewing. Boundary conditions must now be added.
Boundary Conditions / Forces
First, the we need to assign the center pole to the Force computation. Click Next Step > Fix > Force Computation. Select the center pole and click the +. Leave all other setting in default condition.
Now the current condition for the stranded coil needs to be selected. First click Next Step > Add > Electromagnetic Conditions > Current. Click on the left side of the coil. Go down to the bottom left corner and click on the plane behind the front one. If the plane does not show up click on the other side of the coil. The selected plane is seen below.
Click the “+” next to cross-sectional face or body. Input 5 A for the Operating Current and 200 for the Number of Conductors.
