A bar magnet has no marking to incicate its poles . How would you find out near which end is its north pole located ?

   T

tie a

• Tie a thread in the middle of a bar magnet and suspend it freely from a stand
• The magnet will come to rest in the north - south direction
• The pole that indicates the north direction is the north pole of a magnet
• The pole that inicates the south direction is the south pole of a magnet

There are two ways:-

1. Take a thread and tie in the middle of the bar magnet you need to find the poles and suspend it freely. Then The magnet will come to rest in the north - south direction. The pole pointing towards north is the north pole and the pole facing the south , it is the south pole.
    
2. Take a magnet in which already th poles are found and let it indicate magnet A and the other magnet (in which you have to find the poles) as B. Now bring the north pole of the magnet A towards any pole of the magnet B. If it shows repultion then the pole you are testing in the magnet B is north and if it shows attraction it is south pole of the magnet B.
   
   Hope understood as I dont explain properly.. :)

the red is north and the blue is south

Suspend the magnet with a thread and wait until it comes to rest. The side of the magnet which points to the geograohical - north is the magnet 's North Pole and the other side facing the geograohical - south is the South Pole.

If u understand plz give me thumbs up.
