North Pole
What is the origin behind Earth's Magnetic field producing the north Pole and the South Pole?
The earth has a magnetic North and a magnetic south pole to which the compass points. But how does it happen to be that way. What creates the magnetic field within itself.
Iron core, plus the fact that the core is molten. It spins at a different rate than the mantel, creating the magnetic field. Some say that this may be why Mars is currently "dead". The planet cooled to the point where the core solidified and Mars lost its magnetic field. This allowed harmful radiation from the sun to reach the surface and poof! Goodbye lifeforms.
North Pole
When standing at the North Pole, which direction is North?
Since to my understanding North is the direction pointing to the North pole, it seems like when you are actually at that point, North would be undefined since there is no direction to point to. If however, North is defined in reference to South, then it would be pointing up from the North pole - which is actually away from the North Pole. It therefore seems to me like it is undefined at that point?
You can think of the Earth's magnetic field as radiating from the end of the pole, and looping back to the South Pole. Therefore when you are standing at the North pole your compass would be pointing down...
