  Considering the magnetic field response of the QGP medium, we perform a
systematical study of the chiral magnetic effect(CME), and make a comparison it
with the experimental results for the background-subtracted correlator $H$ at
the energies of the RHIC Beam Energy Scan (BES) and LHC energy. The CME signals
from our computations show a centrality trend and beam energy dependence that
are qualitatively consistent with the experimental measurements of the charge
dependent correlations. The time evolution of the chiral electromagnetic
current at the RHIC and LHC energies is systematically studied. The dependence
of the time-integrated current signal on the beam energy $\sqrt{s}$ with
different centralities is investigated. Our phenomenological analysis shows
that the time-integrated electromagnetic current is maximal near the collision
energy $\sqrt{s} \approx 39$ GeV. The qualitative trend of the induced
electromagnetic current is in agreement with the CME experimental results at
the RHIC and LHC energies.
