Bifurcation with the strength of magnetic field.
Variation of WVF2,3 (WVF2) and WVF3,2 with axial (left column) and transverse (right column) magnetic field strength. Shown are (a,b) time-averaged, dominant amplitudes 
of the radial velocity field at mid-gap contributed from the axisymmetric mode 
, the 
mode 
and the 
mode 
, respectively. (c,d) The corresponding time-averaged frequency  
of the complex mode amplitudes 
. Symbols are for eye guidance (the same for subsequent figures), but calculations were typically done for many more parameter values. All presented solutions are stable. The vertical dashed (dotted) lines indicate the critical magnetic field strength in 
at which the WVF3,2 (WVF3,2) flow changes its direction of rotation (cf. Fig. 3): 
for 
, 
for 
, 
for 
and 
for 
. Note that the events 
at 
and 
at 
do not reverse the rotational direction of the respective wavy flows (See, Figure 3).
