 The compass is one of the oldest navigation tools in history. Ever since mankind has gained a greater understanding of navigation and orientation, these tools have been one of the most important navigation tools in important journeys such as the first transoceanic journeys and traveling around the world. None of these journeys would be possible without the aid of a compass in making navigational calculations over long distances. Early explorers had to use local landmarks and stars to navigate, which made traveling to distant or unknown destinations very difficult. The compass was one of the major breakthroughs that made such journeys a reality. In this article, we talk about how the compass works. The online compass works by detecting the Earth's natural magnetic fields. As you know, the earth has an iron core, which is partly liquid and partly solid crystal due to gravitational pressure. Motion in the liquid outer core is believed to be what generates the Earth's magnetic fi
