Abstract
We derive formulas for critical field strengths from variational criteria for field-induced instabilities for nematic liquid crystals. We use these criteria to obtain analytical and numerical results for the Preedericks transition which shows that the spatially homogeneous solution is unstable to three-dimensional modes for magnetic field strengths smaller than that previously predicted by one-dimensional analyses.
