The system created in non-central nucleus-nucleus collisions possesses
large orbital angular momentum. Due to this, particles produced in such
a system can become globally polarized along the direction of the
system's angular momentum. We present global polarization measurements
for $\Lambda$ and $\bar\Lambda$ hyperons in Pb-Pb collisions at
$\sqrt{s_{\rm NN}}=2.76$ GeV performed with the ALICE detector at the
LHC. The global polarization is studied at different collision centralities as well as
at different transverse momenta and rapidity regions of the hyperons.
