Sailors have been using magnetic compass since ancient times to navigate vast oceans and seas. The earth is known to produce a magnetic field which makes the compass needle point towards the north or south poles of earth.
How to Make a Compass with a Needle :
Today these compasses are widely used in aircrafts and ships to detect the directions. The compass needle science experiment is quite an amazing experiment which will make us familiar with the working of a compass. The purpose of experiments like these is to make it easy for the kids to understand science in a more practical and interesting manner.
To perform compass needle science experiment you will have to follow certain easy steps. All you will need is a sewing needle, bar magnet, glass of water and a small piece of cork. Rub the needle against bar magnet to magnetize it. Now take a cork and cut a small circle from it. You can now drive the needle through this cork from one end to the other. Children need to be careful while using a needle. Take a glass filled with water and then make this cork with needle float on it. Place this glass on a table and observe carefully. Soon you will see that the needle will point towards the north and south. Every time you rotate this needle, it will align itself to the same position. This experiment demonstrates the magnetic field of earth.
You might have seen that the compass and needle science experiment is pretty easy to conduct and does not require much effort. School kids can perform this amazing experiment at their homes or they can show it to their friends. Teachers can demonstrate this compass needle science project to their students.
Conclusion: This article showcases the compass needle science experiment which is pretty amazing experiment for the kids. It is based on the principle of earth’s magnetic field and shows us how the magnetized needle responds to it.
