  We conduct a series of magnetohydrodynamical (MHD) simulations of magnetized
interstellar medium (ISM) disturbed by exploding stars. Each star deposits a
randomly oriented, dipolar magnetic field into ISM. The simulations are
performed in a Cartesian box, in a reference frame that is corotating with the
galactic disk. The medium is stratified by vertical galactic gravity. The
resulting turbulent state of ISM magnetized by the stellar explosions is
processed with the aid of Fourier analysis. The results leads to the conclusion
that the input of magnetic energy from exploding stars is additionally
multiplied by differential rotation. The resulting magnetic field appears to
grow up in small-scale component, while the total magnetic flux remains
limited. Our results indicate that magnetic field originating from exploding
stars can be a source of initial magnetic fields for a subsequent dynamo
process.
