Hint: It is found the magnitude of the magnetic field is maximum near the poles and decreases as we go away from the poles. Higher the magnitude of the magnetic field, greater will the force of attraction towards other magnet or any other metal.
Complete answer:
A magnet is a substance that shows some magnetic properties. A magnet attracts metallic substances like iron. A magnet consists of two poles called magnetic poles – magnetic north and magnetic south pole. The magnetic poles are responsible for the magnetic field lines. The magnetic field lines are in the form of closed loops, passing through both the poles of the magnet.
In case of a bar magnet, the magnetic fields lines pass through the magnet and the magnetic poles are at the ends. They appear to be coming out of the north pole and going in through the south pole of the magnet. It is found the magnitude of the magnetic field is maximum near the poles and decreases as we go away from the poles. Higher the magnitude of the magnetic field, greater will the force of attraction towards other magnet or any other metal.Therefore, when we dip a bar magnet in iron filings, the poles of the magnet attract most of the irons filings.
Hence, the answer to the question is that the ends of the magnet that have more iron filings sticking to it are called magnetic poles.
Note: The magnetic poles of a magnet are similar to that of the charges on the dipole. The like poles attract each other and the opposite (unlike) poles repel each other. This means that a north will repel another north pole but it will attract a south pole of another magnet.
