  The dynamical correlation of density fluctuation in quark gluon plasma with a
critical end point has been investigated within the scope of the
M\"uller-Israel-Stewart theory in the presence of static ultra-high external
magnetic field. The dynamic structure factor of the density fluctuation
exhibits three Lorentzian peaks in absence of external magnetic field- a
central Rayleigh peak and two Brillouin peaks situated symmetrically on the
opposite sides of the Rayleigh peak. The spectral structure displays five peaks
in presence of the magnetic field due to the coupling of the magnetic field
with the hydrodynamic fields in second-order hydrodynamics. The emergence of
the extra peaks is due to the asymmetry in the pressure gradient caused by the
external magnetic field in the system. Interestingly, it is observed that near
the critical end point, all the Brillouin peaks disappear irrespective of the
presence or absence of the external magnetic field.
