Abstract

The Sun is a natural site for a dynamo. In fact, the dynamo concept was introduced by Larmor in his 1919 report to the British Association for Advanced Science entitled”How could a rotating body as the Sun become magnetic?” Cowling’s famous anti-dynamo theorem appeared in his paper ”Magnetic fields of sunspots” (MNRAS. 94, 39 ,1934). Yet the origin of the Sun’s magnetic field is not well understood. Some scientists still challenge the dynamo as the source of solar magnetic field [7].
