What is it about?
The motion of the solar surface in the polar magnetic flux powers the solar magnetic fields. The magnetic fields are in a thin sheets of magnetic field near the surface, We explain how the sheets are formed and how they make the observed magnetic fields.

Why is it important?
The paper explains that the magnetic activity is decreasing because the northern and southern solar hemisphere are rotating at differing speeds. In the passed the climate cooled when this happeneds.
Perspectives
The magnetic sheets are formed based on a well established minimum energy.principle. The sheets leaving the surface every 11 years causes the other activity, which is now much easier to explain.
