    "abstract": "We propose the Aharonov-Casher (AC) effect for four entangled spin-half\nparticles carrying magnetic moments in the presence of impenetrable line\ncharge. The four particle state undergoes AC phase shift in two causually\ndisconnected region which can show up in the correlations between different\nspin states of distant particles. This correlation can violate Bell\u0027s\ninequality, thus displaying the non-locality for four particle entangled states\nin an objective way. Also, we have suggested how to control the AC phase shift\nlocally at two distant locations to test Bell\u0027s inequality. We belive that\nalthough the single particle AC effect may not be non-local but the entangled\nstate AC effect is a non-local one.",
