A compass is an instrument which is used to
find directions. It is mostly used
in ships and airplanes. As a rule, mountaineers also carry a compass with them
so that they do not lose their way in unknown places.
The compass has a magnetic needle that can
rotate easily. The marked end of the needle is the North Pole of the magnet. Can you use magnetic compass to find west
direction? Ask your teacher to
help you in using magnetic compass.
