A METHOD FOR INVESTIGATING THE BEHAVIOR OF LIQUID CRYSTALS IN VARIABLE ELECTROMAGNETIC FIELDS

Abstract

. We present a method for measuring optical transmission in crossed polarizers of a nematic liquid crystal layer under the action of rotating magnetic and variable electric fields. The behavior of a nematic liquid crystal in such fields is considered. An experimental setup implementing the method is designed, where the rotating magnetic field is generated between two NdFeB (neodymium–ferrum–borum) disks installed on a rotating platform. The measurement results of the optical transmission in LC-1289 and the estimates of homogeneity of the magnetic field between the disks are presented.
