< p >中太阳耀斑是等离子体,所以不像发生在地球的核心。外核流体高度导电,低粘度,所以变化可能发生在核心领域,但地幔有足够的导电性来过滤掉更多的快速变化(大约一年的时间或者更少)。看到< a href = " https://books.google.com/books?hl=en&lr=&id=96APl4nK9lIC&oi=fnd&pg=PR13&ots=O7fUw9M43s&sig=qQnld9cRXy9X1pUcGJn1MVvLjmI#v=onepage&q=filter&f=false" rel="noreferrer">Merrill and McElhinny pp 49-51 for details. However, geomagnetic jerks have been observed. These are abrupt changes in the second time derivative of the Earth's magnetic field. Sometimes they are global, although mantle filtering can delay the jerk by different amounts at different locations on the Earth's surface.
