# Examples

Each example is a folder in the repository's [`examples/`](<https://github.com/femforge-io/femforge/tree/main/examples>): a script that builds a small model, solves it and opens the result in the workbench. Clone the repository, start Docker and run one from the repository root; [Install](<https://docs.femforge.io/overview/install/index.md>) covers uv and Docker.

```console
uv run examples/thermal/main.py
```

The quickstart project is the fourth. `uvx femforge new` writes it anywhere, with no clone.

  A disc magnet pulls on a steel plate across four air gaps, solved on the axisymmetric section and shown revolved into 3D. The project `uvx femforge new` writes.

  A neodymium disc magnet holds a steel ball in a spherical seat. The pull with and without a steel shell around three magnet sizes in 2D, then the 4 mm magnet in 3D, in a workbench that lists each run as it finishes.

  A copper coil inside a steel pot frame pulls a steel plunger toward the frame's bottom plate. The coil is driven by a current density, solved at two air gaps and shown mirrored across the axis.
