  We study electric and magnetic components of the gluon propagators in
quark-gluon plasma in terms of center vortices by using a quenched simulation
of SU(2) lattice theory. In the Landau gauge, the magnetic components of the
propagators are strongly affected in the infrared region by removal of the
center vortices, while the electric components are almost unchanged by this
procedure. In the Coulomb gauge, the time-time correlators, including an
instantaneous interaction, also have an essential contribution from the center
vortices. As a result, one finds that magnetic degrees of freedom in the
infrared region couple strongly to the center vortices in the deconfinement
phase.
