  We have studied the effect of strong magnetic field on the charge and thermal
transport properties of hot QCD matter at finite chemical potential. For this
purpose, we have calculated the electrical ($\sigma_{\rm el}$) and thermal
($\kappa$) conductivities using kinetic theory in the relaxation time
approximation, where the interactions are subsumed through the distribution
functions within the quasiparticle model at finite temperature, strong magnetic
field and finite chemical potential. This study helps to understand the impacts
of strong magnetic field and chemical potential on the local equilibrium by the
Knudsen number ($\Omega$) through $\kappa$ and on the relative behavior between
thermal conductivity and electrical conductivity through the Lorenz number
($L$) in the Wiedemann-Franz law. We have observed that, both $\sigma_{\rm el}$
and $\kappa$ get increased in the presence of strong magnetic field, and the
additional presence of chemical potential further increases their magnitudes,
where $\sigma_{\rm el}$ shows decreasing trend with the temperature, opposite
to its increasing behavior in the isotropic medium, whereas $\kappa$ increases
slowly with the temperature, contrary to its fast increase in the isotropic
medium. The variation in $\kappa$ explains the decrease of the Knudsen number
with the increase of the temperature. However, in the presence of strong
magnetic field and finite chemical potential, $\Omega$ gets enhanced and
approaches unity, thus, the system may move slightly away from the equilibrium
state. The Lorenz number ($\kappa/(\sigma_{\rm el} T))$ in the abovementioned
regime of strong magnetic field and finite chemical potential shows linear
enhancement with the temperature and has smaller magnitude than the isotropic
one, thus, it describes the violation of the Wiedemann-Franz law for the hot
and dense QCD matter in the presence of a strong magnetic field.
