This paper is concerned with the calculation of nonlinear-electrodynamic effects in the field of a rapidly rotating pulsar. For an electromagnetic wave, exact and asymptotic equations of electrodynamic rays and the law thereof are proposed. The time for the nonlinear-electrodynamic delay is shown to be 3.5 times greater than that for rapidly rotating pulsars or pulsars at rest and the angle of nonlinear-electrodynamic bending of rays is shown to be higher by almost 1.7 times.
