magnetic pole, region at each end of a magnet where the external magnetic field is strongest. A bar magnet suspended in Earth’s magnetic field orients itself in a north–south direction. The north-seeking pole of such a magnet, or any similar pole, is called a north magnetic pole. The south-seeking pole, or any pole similar to it, is called a south magnetic pole. Unlike poles of different magnets attract each other; like poles repel each other. The magnetic force between a pole of one long bar magnet and that of another was described by an inverse square law as early as ...(100 of 200 words)
