The software used is CST STUDIO SUITE 2014.
Here is how the model looks
Dimensions are in meters. All magnets are taken to have relative permeability 1.1 and remanence B=1.4 T,
which approx. corresponds to N33 grade NdFeB magnets.

Figure 3. The outer magnet highlighted
The geometry is parameterized with the following parameters:
![Page 5: Simon motor-test-by-cst-studio-suite-2014](https://reader031.vdocument.in/reader031/viewer/2022021416/5877ff5c1a28ab91178b674b/html5/thumbnails/5.jpg)
The parameters are ordered by radii.
innerR1 - Inner radius of the Inner magnet
innerR2 - Outer radius of the Inner magnet
innerR3 – Outer radius of the plurality of magnets around the Inner magnet.
…
h – Height of the model

Notice “Comp. forces on groups of touching shapes” above. If 2 bodies touch, they are treated as a single
body. Forces acting on such bodies are summed up and reported as a single force exerted to one body.
