Yuan Dynasty magnetic compass above
One of the biggest inventions during the Yuan Dynasty was the magnetic compass. It was made out of two parts a metal spoon and a magnetic land stone with a bronze square plate at the bottom. This was one of the most important inventions in China because this helped anybody and everybody get around, so they knew in what direction they were going in. This compass works the same way as all other compasses, the spoon is attracted to the magnetic force inside the earth (the north pole), therefore the spoon would face north and travelers knew where they were headed. Once travelers from the Yuan Dynasty went on voyages and visted other nations, they showed other nations they’re creation the compass, the compass became more popular and later renovated into more modern versions used today.
