Abstract :
We present a model for the description of the magnetostatic interaction between two glass-coated amorphous microwires with positive magnetostriction. We report the results of dipolar field calculations based on this model as well as results of measurements on microwires with their ends separated. We also calculated the switching field variation with fluctuations in microwire dimensions. Experimental results show an insignificant dipolar interaction between two microwires placed next to each other, provided that their ends are bent and separated at a certain distance. Calculated results are in good agreement with the experimental ones.
