A horse shoe magnet like other magnets have a north and a south pole. The only difference is that is shaped like a horse shoe. It is used to attract small toys, pins etc.
If there is a repulsion between A and N then A is North pole and B is South pole of the horse shoe magnet. If B and N repel each other the B is north and A is south of the horse shoe magnet.

When the magnet is free to rotate and its poles are in a horizontal plane, it comes to rest with its poles pointing roughly north and south.
The poles of a magnet are the ends of the core of the magnet, where the lines of force emerge. An experiment with iron filings shows the lines of force, by putting a sheet of paper over the magnet and sprinkling fine iron filings. This is an easy thing to do at home. For a bar magnet the poles will be at opposite ends. If you have two such magnets you can experiment and find that like poles repel, opposite poles attract.
The strongest magnet contains neodymium a rare earth metal with atomic number of 60.
the poles of the magnet can pick the most iron fillings. Take a magnet. Roll it into a piece of paper and scrub it in the sand, and you will find all the iron fillings connected to the poles..

The positive side of the magnet always points towards the north while the negative side will be in the opposite direction.
we can find the poles of a ring magnet by tieing thread along the circumference of it and suspend it with a torsionless string then it will allign itself according to earth magnetic field
The poles of the earth are magnetic, and since a compass is ideally a magnet, it is always attracted to the North pole. It concerns me that a.) You did not learn this in 7th grade science and b.) that you didn't have the motivation to google this, as it's not like the answer is hard to find.
If possible cover the magnet with a sheet of paper and gently sprinkle the iron filings over the sheet ot paper, they will stick in a pattern following the magnetic "lines of flux" which will get closer and closer near the poles of the magnet. Afterwards you can cleanup by lifting the sheet of paper off of the magnet and the filings will fall away. Without the paper the filings will usually become tightly stuck to the magnet, making it hard to clean.
If you roughly know where North is, tie the bar magnet to a piece of thin string so it balances horizontally and let it dangle. Once it stops spinning and waving about, one end should point North. Mark this end as with an N for north.
