Rajnish · Accepted Answer

make your own compass
magnetise an iron needle using a bar magnet take a small piece
of cork or foam and insert the magnetised needle through it Take a
cup filled with water and let the coark float on it make sure that
that the needle doesnt touch the water ,now your figure compass is
ready to work note the direction in which the needle points when
the coark is floating rotate the cork in different directions note
the direction in which the needle points when the cork begins to
float again without rotating we see that the needle always points
in the same direction,when the cork floats without rotation
