Bifurcation of conical magnetic field.
A strong magnetic field develops via bifurcation in a flow with accretion, as analytical and numerical solutions of magnetohydrodynamic equations show. Examples are swirl-free and swirling jets, and thermal convection near a point source of heat and gravity. The features of the resulting conical similarity magnetic flows are analogous to those observed in cosmic jets.
