FIELD: physics.SUBSTANCE: pressure force arising between two ferromagnetic samples, between which a piezoelectric sensor connected by its outputs to a piezoelectric emf metre is placed, is measured. The ferromagnetic samples are entered into a magnetic gap with a saturating magnetic field with entry speed V, the value of which is matched with the constant of relaxation of magnetic viscosity ? of the ferromagnetic material and length L of the magnetic gap with the saturating magnetic field according to the expression V=L/e?, and the size l of the ferromagnetic samples in their direction of movement in the magnetic gap with the saturating magnetic field is selected to be many times smaller than the size L of that magnetic gap.EFFECT: wider range of means of measuring dynamics of magnetising ferromagnetic material.4 cl, 5 dwg |
