A theory of magnetically domain model for the glass-coated amorphous microwire is studied. The obtained theoretical results are confirmed by experiment. Cast glass-coated amorphous microwire with a posi- tive magnetostriction has a rectangular hysteresis loop, which is characterized by a coercive-force stable mag- nitude. The coercive-force magnitude and the fluctuations of this magnitude are of theoretical and practical interest. The theory of the relaxation mechanism of magnetic reversal is constructed. For a more precise comparison of the theory with the experiment a series of the experimental measurements is needed, which are also discussed in the paper.
