Magnets and methods of their manufacture are disclosed for use in flywheel assemblies, such that the magnets (1208, 1222) comprise oriented fibers, such as, for example, axially-oriented fibers in a flexible rotor magnet composition to predictably allow the magnet (1208, 1222) to expand dimensionally upon rotation only in a predetermined and predictable fashion while maintaining critical contact with a rotor surface. |
