  An SU(2) gauge theory is broken to U(1) by an adjoint scalar to produce
magnetic monopoles. At a lower scale, this U(1) is further broken by a
fundamental scalar to produce tubes of magnetic flux. We dualize the resulting
theory to write an effective theory in terms of the macroscopic string
variables. The monopoles are attached to the ends of the strings, and the flux
is confined in the tubes.
