Question 28

Multiple Choice

Two pairs of associated sunspots appear on the visible disk of the photosphere of the Sun, one pair in each hemisphere. If the magnetic polarity of the westernmost spot in the northern hemisphere is found to be N, what will be the magnetic polarities of the other three spots?


A) The magnetic polarity of all the spots at this time will be N because polarity of sunspots changes only every 11 years.
B) The magnetic polarity of the other northern spot will be N, while in the two spots in the southern hemisphere it will be S.
C) The magnetic polarity of the other northern spot will be S, and the southern hemisphere spots will match this alignment; the westward spot will be N, while the eastward spot will be S.
