  1. The north magnetic pole, also known as the magnetic north pole, is a point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down).

  2. A geomagnetic reversal is a change in a planet's dipole magnetic field such that the positions of magnetic north and magnetic south are interchanged (not to be confused with geographic north and geographic south).

  3. The geomagnetic poles are antipodal points where the axis of a best-fitting dipole intersects the surface of Earth. This theoretical dipole is equivalent to a powerful bar magnet at the center of Earth, and comes closer than any other point dipole model to describing the magnetic field observed at Earth's surface.

  4. A magnet's North pole is defined as the pole that is attracted by the Earth's North Magnetic Pole when the magnet is suspended so it can turn freely. Since opposite poles attract, the North Magnetic Pole of the Earth is really the south pole of its magnetic field (the place where the field is directed downward into the Earth).

  5. Magnetic pole may refer to: One of the two ends of a magnet; Magnetic monopole, a hypothetical elementary particle; The magnetic poles of astronomical bodies, a special case of magnets, especially: The North Magnetic Pole of planet Earth, a point where the north end of a compass points downward

  6. 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

  7. El polo norte magnético es la dirección que señala la aguja imantada de una brújula, dirección que no coincide con la del polo norte geográfico, excepto en los puntos del hemisferio norte, situados en el mismo meridiano que el norte magnético.
