How did the compass make life easier?

Sailors had to keep the shore in sight so they could see landmarks, or they risked getting lost. Compasses made it possible for explorers to sail far out into oceans and away from land—no matter what the weather was like. This led to more exploration, the discovery of new countries, and trade with other cultures.

Why is a compass useful?

The compass is used for navigation, location and direction. People use it to find their way, whether it is on a hiking trail or on a trip to a new location. It is an instrument composed of a suspended magnetic pointer that is attracted to the polarity of the North Pole.

How was the compass improved?

In 1745 Gowin Knight, an English inventor, developed a method of magnetizing steel in such a way that it would retain its magnetization for long periods of time; his improved compass needle was bar-shaped and large enough to bear a cap by which it could be mounted on its pivot. The Knight compass was widely used.

How did the compass help sailors?

The magnetic compass was an important advance in navigation because it allowed mariners to determine their direction even if clouds obscured their usual astronomical cues such as the North Star.
