Abstract
It is shown that under conditions in which a torsion pendulum with ferromagnetic suspension thread oscillates with torsional oscillation being excited by the energy transferred from an a-c magnetic field, Barkhausen discontinuities are released by the torsional deformations. A study is made of the dependence of the voltage pulse, which induced these Barkhausen discontinuities in the coil in the field of which the ferromagnetic suspension thread is placed, on the intensity of the a-c magnetic field, the amplitude of torsional deformation and the angle of phase shift between these two sine quantities. The influence of an underlying longitudinal d-c magnetic field on these Barkhausen discontinuities is also investigated.
