A discussion of the theoretical difficulties in creating a sunspot model. The author reviews current theories of sunspots and concentrates on the strengths and weaknesses of Deinzer's approach. He then evaluates the sunspot problem from the point of view of small magnetic Reynolds numbers, which allow for slippage between the flow and the magnetic field. The analysis is based on recent laboratory experiments with liquid metal, which are predictable with a theory allowing for the damping of the turbulence and, therefore, of the mixing length as a function of the magnetic field. 17 pp. Bibliog.
