It was found that the form of the amplitude dependence of low-frequency internal friction in quenched and aged 5N-purity Al changed under the effect of weak magnetic field pulses (H ≥ 105A/m). That is, the general level of internal friction increased. This effect was attributed to the influence of the magnetic field on structural complexes made up of dislocations and point defects (the role of point defects was played by vacancies).
