Sculpture depicting an early Chinese invention: the magnetic compass. The spoon-shaped needle is also called a lodestone, made from ferrites (magnetic oxides).
The phenomenon of magnetism was discovered in ancient China. That discovery led to development of the compass in China. By the eleventh century the compass was in use in navigation and would be a tremendous aid to ocean-going vessels.
