We show that axisymmetric magnetized winds emanating from rotating stars, disks, tori, etc. generally tend to collimate along the symmetry axis and conjecture that this is the reason there are so many bipolar flows and jets. The actual form of the flows at large distances from the source are either cylindrical or paraboloidal depending on the total poloidal current.
