A digital automated coercimeter comprises a control block, linear current generator, Helmholtz coil, connected in series flux-gate meter, flip-flop, AND gate, pulse counter, digital indicator, generator of clock pulses, threshold block, pulse divider, peak detector, differentiating circuit. Additionally there is placed a generator of alternating decaying current connected by the first contact group of time relay to Helmholtz coil that is connected to the linear current generator by the second contact group of time relay connected to the control block. This makes it possible to increase the accuracy of measurement of coercitive force due to preliminary demagnetization of the article.
