All about The Compass
The magnetic compass was invented in China and was used for fortune-telling and later for navigation. A magnetised needle, or a piece of lodestone, lines up with Earth's magnetic field and points roughly towards magnetic north.
Compasses helped sailors navigate far from land, especially when the sky was cloudy. Europeans later improved compass designs, and the compass became essential for exploration and travel across oceans.
