Understanding what causes the solar cycle requires delving into the complex interplay of plasma physics, magnetic fields, and differential rotation deep within the Sun's interior. The dynamo converts kinetic energy from fluid motion into magnetic energy, amplifying and sustaining the Sun's magnetic field over time.
Solar Cycle Magnetic Field Line Drag: How Shear and Turbulence Twist the Sun's Magnetism
During periods of high activity, the solar wind carries a more complex and turbulent magnetic field into interstellar space. Theories and Ongoing Research.
This shear motion acts like a cosmic blender, stretching and twisting the magnetic field lines, converting poloidal magnetic fields (north-south) into toroidal fields (looping east-west). This turbulent convective motion drags the Sun's magnetic field lines along for the ride.

These stressed magnetic fields rise through the convection zone, eventually breaking through the surface to form sunspots, the visible indicators of peak solar activity. Compounding this effect is the Sun's differential rotation, where the equator spins faster than the poles.
