In a highly conducting plasma convection is hindered by the imposition of a magnetic field. Convection may set in as direct or overstable modes and behaviour near the onset of instability depends on the ratio of the magnetic to the thermal diffusivity. Vigorous convection produces local flux concentrations with magnetic fields that may be much greater than the equipartition value. The interaction between magnetic fields and convection can be observed in detail on the sun and is essential to any stellar dynamo.
