Question

given a bar magnet how will you find the west direction

Answer 1

A compass is an instrument that is used to find direction. A compass is created by placing a lightweightmagnet on a nearly frictionless pivot point. The magnet is generally called a needle. One end of the needle is often marked "N," for north, or colored in some way to indicate that it points toward north.
