From: Magnetic field induced flow pattern reversal in a ferrofluidic Taylor-Couette system
Flows in the presence of an axial magnetic field (cf.Fig. 5).
Contours of flows for 
values as indicated. (a) Contour of the radial velocity 
on an unrolled cylindrical surface in the annulus at mid-gap. The arrows below illustrate the rotational direction. (b) Contour of the velocity component 
in the 
plane at mid-height. (c) Vector plots 
of the radial and axial velocity components in a constant θ plane, with color-coded azimuthal vorticity η from red (minimum) to yellow (maximum). See also movie files movie3.avi and movie4.avi in SMs.
