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 field flip, and then flip back again every 11 years. The strength of the magnetic fields also varies over the cycle, but the polarity shift is the most significant change.
