The Magnet Compass Research Paper

Many people believe that the magnetic compass is one of the most important inventions ever created, next to penicillin and the panini maker. It turns out that there is an entire story that lies behind this marvelous invention’s history and how it works.

The early compass was also used for people who performed Feng Shui, so they could align their furniture accordingly.

Even today, the compass is still a important tool for many people. For that, we owe a big thanks to the Chinese for creating such a wonderful invention. From now on, when looking at the small, versatile compasses of today, just remember that that little thing has come a long way from a spoon on a metal plate....
