Even the Earth, in fact, has a pair of poles: the north and south poles. Overview of Magnetic Poles Magnetic poles are sections on a magnet where the magnetic field is the strongest. They are found on opposite ends. The north pole is found on one end of a magnet, whereas the south ...

For the last 20–30 years, the drift velocity of the north magnetic pole (NMP) has increased by a factor of almost 5. It is unclear whether this is the cyclic process, according to which NMP twice changed the direction of its drift (in 1580 and 1860) and should turn once again in ...
those in a bar magnet, the magnetic moment (m) is defined as the strength of the poles (p) multiplied by the distance between the poles (L), which can be represented by the equation m = pL. The direction of the moment points from the south pole of the magnet to its north pole. ...

If you have a coil of wire, simply curve the fingers of your right hand around the coil in the same direction as the current is flowing. Your thumb will point out of the north magnetic pole which the coil of wire will create.
