    Magnetic Field Reversal and the Schwabe Cycle
    The 11-year cycle, known as the Schwabe cycle, is actually the period between successive solar maxima of the same magnetic polarity. Because the Sun's global magnetic field reverses its polarity at every solar maximum, the complete magnetic cycle—the Hale cycle—spans approximately 22 years. During this reversal, the toroidal magnetic field stretches and then collapses, d…

  5. Sunspot Number

    Linked via "Hale Cycle"

    Sunspots appear dark because they are regions where intense localized magnetic fields inhibit the convective transport of heat from the solar interior to the surface. The temperature difference is generally about $1500 \text{ K}$ cooler than the surrounding photosphere.
    A critical component of solar cycle study is the Magnetic Polarity Reversal. During a solar maximum, the leading spots in active regions adopt a consistent magnetic polarity ($+/$ or $-/$ relativ…
