  We identify the Faddeev-Niemi knot in Skyrme theory as a vortex ring made of
a helical baby skyrmion (a twisted chromomagnetic vortex which is periodic in
$z$-coodinate) with the periodic ends connected together. This allows us to
interpret the knot as two quantized magnetic flux rings linked together, the
first one winding the second $m$ times and the second one winding the first $n$
times, whose linking number $mn$ is fixed by the Chern-Simon index of the
magnetic potential. This interpretation strongly suggests that the Skyrme
theory could also describe a very interesting low energy physics in a
completely different environment, which puts the theory in a totally new
perspective.
