For an actual planetwide polarity reversal to occur, such a reversed flux patch would grow and engulf the entire polar region; at the same time, a similar change in overall regional magnetic polarity would take place near the other geographic pole.

• 如果整个行星的磁极要真的反转，反向通量斑块需扩大到涵盖整个极区；同时，另一个地理极点附近也会发生类似的区域极性全面变化。
