Web8 jul. 2010 · The ancient Chinese discovered lodestones independently, and in addition found that after a piece of steel was " touched to a lodestone " it became a magnet itself. Around the year 1000 (or earlier, according to some sources) the Chinese discovered another strange (but very useful!) property of magnets. WebHumans discover the magnetic lodestone as well as the attracting properties of amber. Advanced societies, in particular the Chinese and the Europeans, exploit the properties of magnets in compasses, a tool that makes possible exploration of the seas, “new worlds” and the nature of Earth’s magnetic poles. c. 600 BC c. 100 BC c. 50 BC 1086 1180 1269
