We have studied theoretically the interaction between two ferromagnetic microwires as a function of their geometrical parameters, such as length and radii. The analytical results has been contrasted with experimental observations of two amorphous Fe77.5Si7.5B15 glass coated microwires (length L = 3 mm and radii R = 7.9 mu m) suspended on the free surface of the liquid (distiller water and ethylene glycol). Then, the resulting dynamics include their magnetostatic interaction and the drag force provided by the viscosity of the liquid.
