text: Solar physicists have long known that sunspot magnetic fields reverse polarity from cycle to cycle.
text: Thus the intense (0.2–0.4 tesla) localized fields of sunspots are gradually dispersed to form weak (1–2 × 10–4 tesla) polar fields, which reverse polarity (not necessarily synchronously) around sunspot maximum.
text: Thus the intense (0.2–0.4 tesla) localized fields of sunspots are gradually dispersed to form weak (1–2 × 10–4 tesla) polar fields, which reverse polarity (not necessarily synchronously) around sunspot maximum.
text: Each time the sunspot count rises and falls, the magnetic field of the Sun associated with sunspots reverses polarity; the orientation of magnetic fields in the Sun's northern and southern hemispheres switch.
