Scientific paper

The buoyancy of a magnetic field is calculated within the framework of mean field magnetohydrodynamics. The buoyant velocity is a nonmonotonic function of the magnetic energy density. Its initial increase with field strength gives way to a decrease for strong fields. The decrease is brought about by magnetic line tension, usually ignored in descriptions of flux tube buoyancy. The saturation of buoyancy weakens substantially the restrictions imposed by this effect on space dynamo models. The period of buoyant rise from the bottom of the convective shell to the solar surface is at least six years for a field of arbitrary strength.
