It is magnet with which a compass is made of and when it comes to the description of compass, it can be described as a navigational instrument that helps you to find direction if you are unable to find it. The device is of great help in maritime trade and also responsible for the increase of the trade the world over as it helps the sailors to find direction with which they reach to their destination with ease.

The magnet that the compass made of helps it to point free and align accurately with the magnetic field of earth. The cardinal points of a compass are east, west, south and north.

When it comes to the invention of the equipment, it is invented in the third century in China and considered as among the best inventions that have ever happened to the humanity.

Construction of a compass
[edit] Magnetic needle

A magnetic rod is required when constructing a compass. This can be created by aligning an iron or steel rod with Earth's magnetic field and then tempering or striking it. However, this method produces only a weak magnet so other methods are preferred. For example, a magnetised rod can be created by repeatedly rubbing an iron rod with a magnetic lodestone. This magnetised rod (or magnetic needle) is then placed on a low friction surface to allow it to freely pivot to align itself with the magnetic field. It is then labeled so the user can distinguish the north-pointing from the south-pointing end; in modern convention the north end is typically marked in some way, often by being painted red.
[edit] Needle-and-bowl device

If a needle is rubbed on a lodestone or other magnet, the needle becomes magnetized. When it is inserted in a cork or piece of wood, and placed in a bowl of water it becomes a compass. Such devices were universally used as compass until the invention of the box-like compass with a 'dry' pivoting needle sometime around 1300.
