Damien is right. The magnetic field flips every 11 years or so. This
length has been approximately constant in the last few hundreds years,
since astronomers started to keep track of it. There seem to be a lot of
other cycles superimposed, some shorter, some much longer. Anyway the
11-years one is the most evident.
