N2 - In this article, the rotation of freely suspended nematic liquid crystal (5CB) film under applying electric field and current is reported and also investigate the polarization of light beam passing through the film. The rotation of freely suspended liquid crystal generating under external electric field when an electric current perpendicular to external field is passing through it. The LC between two crossed polarizes is a technique to produce linear polarizer light with axial symmetry. M3 ER -
