In 1933 Cowling wrote an article, The magnetic field of sunspots. Joseph Larmor had worked in this area, arguing that sunspots regenerate themselves through a dynamo effect. Cowling showed that Larmor's explanation was incorrect. His article assured him of a good reputation in the field of astrophysics.
