My project relates to social studies in that the history of the poles affecting human communications and the use of magnetism in the utilization of electric and magnetic currents. Many years before the initial invention of GPS tracking systems and global tracking satellite dishes, humans relied on the power of electro-magnetic waves to navigate the earth: more specifically the earth's oceans. One of the most important of these inventions was the common compass. The compass has a metal needle, and in each ninety degree part of the compass is an electromagnet. Whenever the compass's user pulls out the compass the needle will be pulled by the north electromagnet. This single device has altered the course of history, from European explorers discovering the north and south American continents, to traders across Asia and the Mideast finding their way towards Europe along what became known as the silk road. It relates to the invention and foundation of magnetics in order to help build and control space craft during NASA's space program during the 1960's and 1970's. In recent years electromagnetism has been used to help power elevators, trains and even some automobiles. During world war 2, when experimentation was at an high for weaponry, guns in Germany were being tested to see if a magnetic action bolt would fire faster, though the rifle never made it to production. At the core electromagnetism is "magnetism", first discovered by Greek philosophers and scientists, Aristotle and Thales. Over the course of the centuries, during the 11th century, Chinese scientist Shen Kuo was the first man to write of the magnetic needle compass by using the astronomical concept of true north, a device that would revolutionize the world of travel. The electric concept was first found by Benjamin Franklin in the 18th century.
