Magnetic Compass
The magnetic compass was invented in medieval Europe in the 1302. Since travelers during that time kept getting lost; the compass directs travelers in different directions such as North by aligning itself with the Earth’s magnetic field. It also includes directions that are a combination of 2 major directions, such as North-East. The magnetic compass was invented to keep travelers from getting lost. This technology has benefited society by pointing airplanes, ships and travelers in the right direction and prevents them from going astray.
