  We display in $SU(5)$ the presence of an electroweak monopole and a magnetic
dumbbell ("meson") made up of a monopole-antimonopole pair connected by a
Z-flux tube. The monopole is associated with the spontaneous breaking of the
weak $SU(2)_L$ gauge symmetry by the induced vacuum expectation value of a
heavy scalar $SU(2)_L$ triplet with zero weak hypercharge contained in the
adjoint Higgs 24-plet. This monopole carries a Coulomb magnetic charge of
$(3/4) (2\pi/e)$ as well as Z-magnetic charge, where $2\pi/e$ denotes the unit
Dirac magnetic charge. Its total magnetic charge is $\sqrt{3/8}(4\pi/e)$, which
is in agreement with the Dirac quantization condition. The monopole weighs
about 700 GeV, but because of the attached Z-tube it exists in a magnetic
dumbbell configuration whose mass is expected to lie in the TeV range. The
presence of this dumbbell provides an exciting new avenue for testing grand
unified theories such as $SU(5)$ and $SO(10)$ at high energy colliders.
