Poles of a Magnet If we take a bar magnet and dip it into iron filings, it will be observed that the iron filings cluster about the ends of the bar magnet. The ends of the bar magnet are apparently points of maximum magnetic effect and for convenience we call them the *poles of the magnet. A magnet has two poles viz north pole and south pole. In order to determine the polarity of a magnet, suspend or pivot it at the centre. The magnet will then come to rest in north-south direction. The end of the magnet pointing north is called north pole of the magnet while the end pointing south is called the south pole. The following points may be noted about the poles of a magnet :
