The dependence of the dislocation stopping force upon the dislocation velocity and the magnetic field intensity in a normal metal at low temperatures was investigated. It was shown that the dependence of this force upon the dislocation velocity was a non-monotonic function, with a local minimum and maximum. The positions of the maximum and minimum of the stopping force were independent of, and dependent upon, the strength of the magnetic field, respectively. Dislocation motion was unstable in the velocity range where dF/dv < 0, where F and v were the dislocation stopping force and velocity, respectively.
