The Earth isn't completely spherical - land at the North Pole is a number of kilometres nearer to the core of the planet than land at the Equator.
事实上，气球并非是一个完美的球体，北极地区要比赤道地区更加接近地心，两地之间的这一差距大概是在数公里。
Changes in the thickness, viscosity and conductivity of the outer core in the past could have led to convection patterns that caused the magnetic pole to tilt.
过去任何来自于核外层的厚度、粘性和导电性变化都会导致对流形式变化从而引起磁极倾斜。
The pole configuration at the S-pole side is arranged so that S-side magnet poles are coaxial to N-side core poles, and vice versa.
S极边的极配置是这样安排的，即S 极边的磁极与N 极边的铁极同轴，反之亦然。
