Was Figure 14.24 related to the number of sunspots, or just the N-S poles of the Sun?
It is related to the number of the sunspots That picture shows what happens to the Sun’s field lines as the surface of the Sun rotates. The region around the Sun’s equator rotates more quickly, and results in magnetic fields getting pulled and twisted. The rightmost plot shows the situation after things have gotten really twisted up, and field lines are even twisted into little loops. The more twisted up the lines get, the more sunspots there are, and the right plot shows sunspots at the places where magnetic fields are most distorted and looped-up.
