Question

how will you find out the poles of a magnet if you are given one magnet which you don't know the poles another magnet has marked the south and north poles

Answer 1

with the help of bar magnet we can find pole of another magnet has marked the south and North Pole

Answer 2

With the assistance of bar magnet we can discover shaft of another magnet has denoted the south and North Pole.

The contrary shafts of two magnets draw in.

In this way, when the red end of a magnet or compass is pointing north, it is on the grounds that it is being pulled in toward that path by the south end of another magnet (frequently hued blue) – this is the fanciful magnet inside the Earth.
