Magnetic Pole
Magnetic pole is an each of the points near the extremities of the axis of rotation of the earth or another celestial body where a magnetic needle dips vertically.
Magnetic pole is an either of two small regions which are located respectively in the polar areas of the northern and southern hemispheres and toward which a compass needle points from any direction throughout adjacent regions.
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 1750. If, for example, the separation between the two poles is doubled, the magnetic force diminishes to one-fourth its former value.
Breaking a magnet in two does not isolate its north pole from its south pole. Each half is found to have its own north and south poles. Magnetic forces, in fact, cannot be traced to unit magnetic poles of submicroscopic size in direct contrast to electric forces that are caused by actual discrete electric charges, such as electrons and protons. Indeed, magnetic forces themselves also fundamentally arise between electric charges when they are in motion.
