where‘s santa ？

  The earth as a big magnets, so is a magnet poles on both ends of the the two points, or magnetic field lines the most dense that point. The earth itself is like a huge magnet, the magnets have two very, CiZhen south refers to the South Pole position for the north, refers to the north magnetic pole position for. But in fact the earth's magnetic field direction and not pointing to the north and south. The earth's magnetic field is not constant, it's the north and south poles had a position, namely the exchange of geomagnetic North Pole change into geomagnetic South Pole, and geomagnetic Antarctic into geomagnetic North Pole, this is the so-called "pole reversals".
The compass point north and south is equivalent to a small CiZhen parallel in a bar magnet, we would find that, outside a bar magnet and small CiZhen N very pointed direction just the opposite. So, it is known that the magnetic poles of N a geographical the poles of the earth is the S extremely; Geographic pole S very is the earth's poles. The N extremely
  The poles of the earth is the earth as a magnet showed what a S a N. Geographic pole is the earth in geomagnetic field compass referred to a S a direction. N.
I think santa live in the north.because a direction. N may be santa's home .
In this way ,physical south as geographical north .

  Declination is nine deep. there is a morganatic plot,so the real north is 81n rather than 90n . Santa live in north , so he is on 81 n

  So,i think the santa don't live in the north in physical north .
