  Electromagnetic field produced by magnetic multipoles in hyperbolic motion is
derived and compared with electromagnetic field produced by electric multipoles
in hyperbolic motion. The resulting fields are related by duality symmetry.
Radiative properties of these solutions are demonstrated. In the second part an
analogous, uniformly accelerated source of gravitational radiation is studied,
within exact Einstein's theory. Radiative characteristics of the corresponding
solution as flux of the radiation and the total mass-energy of the system are
calculated and graphically illustrated.
