WebThe poles of the Sun are different in several ways from the areas near the Sun's equator. The Sun has a magnetic field with North and South Magnetic Poles. About every 11 years, the Sun's magnetic poles flip - North becomes South and vice versa. This flip happens around the peak of the sunspot cycle, when there are lots of sunspots.
