This paper investigates the bipartite entanglement of a two-qubit Heisenberg XXZ chain under an inhomogeneous magnetic field. By the concept of negativity, we find that the inhomogeneity of the magnetic field may induce entanglement and the critical magnetic field is independent of J z . We also find that the entanglement is symmetric with respect to a zero magnetic field. The anisotropy parameter J z may enhance the entanglement.
