Solar Magnetic Cycle


  - 
    Number of Sunspots increase and
decrease along a period of
11 years.
 
  - 
    Change of polarity of the poloidal and
toroidal field every
11 years.
 
  - 
    A line traced between the center of
the sunspots in a sunspot
pair has a systematic tilt with respect to the East-West Direction,
which
increases with latitude.
 
  - 
    Sunspots appear around 40 latitudes
and migrate towards the
equator as the cycle progresses.
