Where is Santa?

Where is Santa?
     Where is Santa? I think almost people will say he is lives in North Pole, but if I say he is lives in South Pole, am I wrong?
Of couse not, why? That's a confused question. Now let me talk about this question.
    
     We always talk about north, south, west or esat, that basically talk about Geographic, so when we say Santa is lives in North Pole, we mean Geographic North.
    
     In 1600s, British Gilbert discovered earth is covered by an invisble field. It is called the Magnetic Field. It has two magnetic poles: the North Magnetic Pole and the South Magnetic Pole.  Our earth produced own Magnetic Field. We couldn't touch it, we couldn't see it, but this magnetic field is real and exists. Therefore the earth like a huge permanent magnet, also this huge magnet has  two magnetic poles: the North Magnetic Pole and the South Magnetic Pole, but not the same place like Geograp. We can see the image, the notth magentic pole is same place as the south geographic pole, and the south magentic pole is same place as the north geographic pole.
    
     Now let we answer that question again. Where is Santa? I can say he is lives in North, which means the geographic North or I can say he is lives in South, it represents the physical south.
