文摘
- •
Destabilization effect is established in case of axial magnetic field.
- •
Dipolar magnetic field strongly stabilizes the convective flow.
- •
The basic flow loses its stability with respect to non-axisymmetric perturbations.
- •
The instability sets in as oscillatory or steady pitchfork bifurcation.
