## How does a compass know where you’re going?

A compass points north because all magnets have two poles , a north pole and a south pole, and the north pole of one magnet is attracted to the south pole of another magnet. (You may have seen this demonstrated by a pair of simple bar magnets or refrigerator magnets pushed end to end.)

Who uses a compass?

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.

### At which place the compass needle feels as a direction finder?

## Which is an instrument that gives you direction information for navigation?

Generally a ‘compass’ is an instrument, which gives you the direction information for navigation. You must refer Haversine distance formula before going through this post. So if you are from GIS field or dealing with GIS application, you should know bearing and how to calculate bearing with formula. Let us look on formula and tool for bearing:

## What kind of compass can you use to find your direction?

You can use a magnetic compass, which uses the Earths magnetic field, to figure out where you are or in which direction you want to go. Compasses always point north. If you dont have a compass, you can use the sun or the stars. The sun rises in the east and sets in the west.

What happens when you spin around a compass needle?

### Which is the best way to find your direction in the sky?

That means when you’ve identified the North Star in the sky, you know that you’re facing north. From that position, the opposite direction would be south, while east would be to your right and west would be to the left. Using the North Star to find your direction works best on a clear night.
