The 1908 discovery of robust magnetic fields in sunspots made it transparent that the 11-year cycle is the magnetic cycle of the solar. it really is only
during the previous few a long time that significant advancements in plasma physics have finally given us the clue to the origins of the cycle and the way the massive explosions affecting the earth arise.
