  Each of electrically charged particles testifies in favor of the existence of
a kind of the magnetically charged monoparticle. As a consequence, only the
corresponding mononeutrinos answer for quantization of the electric charges of
all neutrinos. Therefore, to understand the nature of matter at the fundamental
level, one must use the electromagnetic field as the field of the unified
system of the photon and monophoton where the electric and magnetic forces of
the nature are united. Some logical and laboratory confirmations of the
availability of compound structure of gauge invariance have been listed which
say also about the connection between the states of elementary particles and
monoparticles.
