Magnetic annealing at 800 °C for 3, 15 and 30 minutes was conducted to evaluate the effect of a 17T magnetic field on the microstructure formation of cold rolled Fe‐0.75 %Si samples. According to texture measurements magnetic field did not seem to significantly affect the development of grains with Goss orientation, however it showed to affect the nucleation and growth process of {001}, {110} and {111} grains by increasing the volume fraction of the η fiber and by decreasing the fraction of the alfa and gamma fibers. ESEM/OIM and optical microscope results indicate that although magnetic field may retard nucleation it also promotes grain boundary displacement and for longer annealing times the retardation effect is compensated by the magnetic filed driving force.
