   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…

   Tokamaks
   The Tokamak (a Russian acronym for "toroidal chamber with magnetic coils") is the leading MCF device architecture. It utilizes a toroidal magnetic field, a poloidal field generated by external coils, and a toroidal current induced within the plasma itself to create a helical, closed magnetic field structure. Stability is predicated on achieving a sufficient safety factor ($q > 1$) to prevent catastrophic plasma disruptions known as '[Magnetic S…
