A study was made of the electron drag force which acted on a moving dislocation in the presence of a strong magnetic field. It was shown that the drag force exhibited a sharp minimum at A = 0; where A was the angle between the dislocation axis and the magnetic field direction. The typical width of the minimum was of the order of V/v, where V was the velocity of the dislocation and v was the Fermi velocity. The minimum was attributed to compensation of the deformation and electromagnetic contributions to electron/dislocation interaction. When A was greater than a critical value, compensation did not take place and the drag force increased linearly with increasing magnetic field strength. The form of the angular dependence of the drag force was in qualitative agreement with experimental data.
