Query: The Freedericksz transition in a spatially varying magnetic field   Much is known about the Freedericksz transition induced by uniform electric
and magnetic fields in nematic liquid crystals. Here we study the effects of a
spatially varying field on the transition. We study the response of a nematic
to a magnetic field with cylindrical symmetry, and find that since the field
magnitude varies in the plane of the cell, the transition vanishes.
