  In this article, we investigate the dynamics of a bipartite system under the
action of a local non-Hermitian system. We study the quantum correlation of the
bipartite system quantified by the entanglement, measurement-induced
nonlocality (MIN) based on Hilbert-Schmidt norm, trace distance, and Bell
inequality. We find that the quantum correlations of the system depend on the
initial conditions and system parameters. We observe that the states with
nonzero quantum correlation obey the Bell inequality even in the absence of
entanglement. Moreover, the Bell inequality completely fails to manifest the
nonlocality for the mixed quantum state. However, we have identified the
nonlocal attributes of the mixed quantum state in terms of MIN and trace
distance MIN. Our results show that the trace distance-based correlation is
more robust against the nonunitary evolution compared to the other quantifiers.
