Abstract

The non-linear Boussinesq equations describing axisymmetric convection in a cylinder with an initially uniform magnetic field have been integrated forward in time numerically. When the field is weak a strong central fluxrope is formed at the axis. In this case the maximum field strength can be limited either kinematically or by dynamical effects, and the equipartition prediction B2max ∼ 4πϱu2 is easily exceeded. If the field is strong oscillations can occur and hysteresis is possible as the field is increased and decreased.
