Purpose: In this paper results of experience of influence a structure (amorphous, amorphous after structural relaxation and nanocrystal) and influence a corrosion medium, which was 1 M solution NaCl, on magnetic properties (initial magnetic permeability μp, relative magnetic permeability μw, coercive field Hc, remanence Br and saturation magnetisation Bs) on Fe63.5Co10Cu1Nb3Si13.5B9 alloy have been presented. Design/methodology/approach: The material was obtained by the method of rapid cooling from liquid phase. The measurements of structure were made on the magnetic balance, the X-ray diffraction. The measurements of magnetic properties were made on the Maxwell-Wien bridge, the fluxometr and the VSM – Vibrating Sample Magnetometer. Findings: The results allowed defining that are significant dependence between the magnetic properties, the structure of the material and the corrosion. Research limitations/implications: Due to the high influence of the corrosion on the magnetic properties of the material further research should be undertaken. Practical implications: The measurements allow giving information to the industry how decrease the magnetic properties of alloy after influence the corrosion medium. Originality/value: The Finemet is very attractive due to his excellent soft magnetic properties. The problem of the corrosion has been presented and her influence on the magnetic properties.
