233 BC. Compass!
233 BC

Archimedes while he was working with a lodestone(a form of the mineral magnetite that is a naturally-occurring magnet and aligns itself with the Earth’s magnetic field) for his planetarium, came up with a new device, the compass. To retain the compass magnetism for long Archimedes used steel “needles”.
