An aspect of the present invention provides a toy assembly system comprising a central compartment configured to house a plurality of toy bodies, each toy body having magnetic hubs arranged in an outer region of the body. The system can include outer compartments that house ferromagnetic outer components (e.g., ferromagnetic spheres) separate from the toy bodies and a release mechanism configured to release during a single operation a single toy body and a set of outer components, wherein the single toy body and the set of outer components self-assemble and automatically align. Another aspect provides a toy track system comprising a launch portion configured to magnetically retain the magnetic vehicle in a launch position, a release configured to release the vehicle from the launch position, and a track portion coupled to the launch portion and configured to guide the released vehicle along a predetermined path.
