Hovering Magnet

This one demonstrates superconductivity. Superconductors expel magnetic fields from their bulk, which has a side effect of exerting an upward force on magnets.


You can spin or bounce the magnet with the mouse. If you push it too far, you'll see that the active part of the superconductor extends beyond its visual representation: superconductivity has only been implemented for an infinite plane and a sphere.


The documentation walks you through the process of building each of the tutorials and includes assets (graphics and GameObjects) for all of the demos.
