As a result of the diamagnetic anisotropy of liquid crystal molecules, nematic order can be produced by the application of a magnetic field. If a magnetic field is applied to a nematic liquid crystal in the isotropic phase then the order is given by: :$\backslash langle\; P\_2\backslash rangle=\backslash eta\backslash mathbf^2$ The proportionality constant $\backslash eta$ is the paranematic susceptibility. The value increases as the liquid crystal is cooled towards its transition temperature. In both the mean field approximation and Landau-deGennes theory the paranematic susceptibility is proportional to $(T-T^$ *_C)^ where $T^$ *_C is the transition temperature. ==References== *E.B.
