A new mode of reorientation of the field of director n̂ of a nematic liquid crystal (LC) encapsulated into a rectangular cell under strong crossed electric (E) and magnetic (B) fields has been proposed. Numerical calculations performed within the linear generalization of the classical Ericksen–Leslie theory show that transition periodic structures facilitating a decrease in the effective rotational viscosity of a nematic, formed by 4-n-pentyl-4'-cyanobiphenyl (5CB) molecules, may arise during reorientation of n̂ at certain ratios of the moments and momenta per unit volume of the LC phase and when E ≫ E{sub th}. The calculations conducted for 5CB also indicate that the periodic structures formed in a LC cell facilitate a decrease in reorientation time τ{sub on} of the director field.
