  We have computed the chiral susceptibility in quark-gluon plasma in presence
of finite chemical potential and weak magnetic field within hard thermal loop
approximation. First we construct the massive effective quark propagator in a
thermomagnetic medium. Then we obtain completely analytic expression for the
chiral susceptibility in weak magnetic field approximation. In the absence of
magnetic field the thermal chiral susceptibility increases in presence of
finite chemical potential. The effect of thermomagnetic correction is found to
be very marginal as temperature is the dominant scale in weak field
approximation.
