Observations have shown that Saturn's magnetic field is remarkably axisymmetric and strongly dipolar. On reviewing three possible explanations for the field generation process we view a Braginskii nearly axisymmetric dynamo model as compatible with both the tilt angle and power requirements in a large Saturnian core. If the core is sufficiently small then a mean field dynamo becomes a more likely candidate, whereas if both these models fail an axisymmetric dynamo based on compressible flow may be possible.
