How does compass help to find direction
Asked by tinapatidar2007 | 24th Feb, 2020, 09:26: PM
A device known as a compass is used as a navigational instrument.
It is usually a small box witha glass cover. It has a dial with directions marked on it, and a magnetised needle is pivoted inside the box, which can rotate freely.
The compass is kept at a place where directions are to be found and is rotated until the north(N)and the south (S) marked on the dial are at the two ends of the needle.
The magnetic needle comes to rest in N-S direction because the north pole of the earth's magnet is attracted to the South pole of magnetic needle and South pole of the earth's magnet is attracted to the North pole of magnetic needle.
The ‘N’ mark on the compass points to the north. North corresponds to 0°.
The angles increase clockwise. So, East is 90°, South is 180° and West is 270°.
