Answer to Question 1

Astronomers measure magnetic fields on the Sun using the Zeeman effect. When an atom is in a magnetic field, the electron energy levels are altered, and the atom is able to absorb photons with a greater variety of wavelengths than the same atom not in a magnetic field. Magnetic images of the Sun show that sunspots contain magnetic fields a few thousand times stronger than Earth's.
