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.
