If you are struggling with the corks or don’t have corks, you can use other items to keep your needle afloat. People have used magnetic compasses for thousands of years to navigate the globe. A compass needle can be made from any piece of metal that can be magnetized. He was mystified by the invisible forces that could deflect the needle in that compass. Specifically, once it stopped moving, the needle should have aligned itself along Earth's magnetic field, lining up along the north/south axis. Materials, Observations and results Make sure you do this in one direction only. Although Earth's magnetic field is relatively weak, it should have clearly affected the needle because the needle was allowed to freely float in the cork disk on the water. This means that one end of the needle should have pointed north, while the other pointed south. Have you ever used a compass to help you figure out what direction you should go? Create a second compass and add it to the same bowl of water. As we do this this arrangement, Bar magnet starts to rotate and finally it shows north pole and south pole.
