This is a tutorial showing how to make magnetizable materials. The wrenches are not magnetic on their own, but they respond to magnetic fields.
You can turn on the magnet by clicking on it. It takes a few seconds to warm up. You can't turn it off again.
The documentation walks you through the process of building each of the tutorials and includes assets (graphics and GameObjects) for all of the demos.
