It was found that the form of the amplitude dependence of low-frequency internal friction in a quenched and aged 5N-purity Al sample changed under the effect of weak magnetic field pulses (H greater than 105A/m): the general level of internal friction increased. This effect was attributed to the influence of a magnetic field on the structural complex formed by a dislocation and point defects (the role of point defects was played by vacancies).
