Answer to Question 1

The Babcock model explains the magnetic cycle as repeated tangling and untangling of the solar magnetic field. Because an ionized gas is a very good conductor of electricity, if the gas moves, the embedded electrical currents and resulting magnetic fields must move with it. As a result, differential rotation drags the magnetic field along and wraps it around the Sun. Rinsing and sinking convection currents then twist the field into ropelike tubes. The model predicts that pairs of sunspots should occur where these magnetic tubes burst through the Sun's surface.
