Alfvén's magnetic field theory

Alfvén's magnetic field theory describes how magnetic fields interact with electrically conducting fluids, like plasmas found in space and stars. He proposed that magnetic fields can influence the movement of these fluids, creating waves called Alfvén waves, which transfer energy along magnetic lines. These waves help explain phenomena such as solar flares and the behavior of the solar wind. Essentially, Alfvén showed that magnetic forces are integral to plasma dynamics and can propagate disturbances through space plasma, shaping magnetic and energetic phenomena in astrophysical environments.
