pic of the day--solar magnetic reversal

Quote:
Regardless of the direction of the main driving current coming into the Sun, the eleven-year reversal of the magnetic loops can be explained by transformer action. If the main magnetic field that induces the surface currents is growing in strength, the surface current will point in one direction. If the main magnetic field starts to weaken in intensity, the secondary (surface) current will reverse direction. Consequently the magnetic polarity of the loops will also reverse. Notice that this mechanism does not require the main solar driving current itself to reverse direction, only to vary in amplitude. It also does not depend on the direction of the primary current.

So the magnetic field of the sun can be weakening, not strengthing, and transformer action will still reverse the magnetic field?
