Hale discovered that sunspots were associated with magnetic fields. What happens to these magnetic fields during a full sunspot cycle?

Question

Quizplus · Accepted Answer

During a full sunspot cycle, the magnetic fields associated with sunspots change polarity. This means that the north and south poles of the magnetic fields switch places. The cycle starts with a period of low sunspot activity and weak magnetic fields, followed by a period of increasing activity and stronger magnetic fields. As the cycle peaks, there are more sunspots and the magnetic fields are the strongest. Then the activity decreases again, and the magnetic fields begin to weaken until the next cycle starts.
