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). During solar maximum, the Sun is riddled with these spots, leading to increased solar flares and coronal mass ejections.

Conversely, during solar minimum, this shielding weakens, allowing more cosmic rays to penetrate inner planetary systems, a phenomenon critical to consider for deep-space missions. The dynamo converts kinetic energy from fluid motion into magnetic energy, amplifying and sustaining the Sun's magnetic field over time.
This process is driven by the motion of electrically conductive plasma, primarily composed of ionized hydrogen and helium. This sunspot number forms the basis for the Solar Cycle Progression, where we move from Solar Minimum, a period of relative calm with few sunspots, to Solar Maximum, a time of heightened magnetic activity.

These stressed magnetic fields rise through the convection zone, eventually breaking through the surface to form sunspots, the visible indicators of peak solar activity. 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.
