   The paper presents unified methodology for testing tensile and compressive stress dependences of ring-shaped magnetoelastic cores. This methodology enables testing of magnetoelastic properties of soft magnetic materials in full range of axial stresses, which is especially important from the point of view of development of physical models of magnetization process under stresses. The paper presents also results of testing the magnetoelastic properties of Fe₂₅Ni₅₅Si₁₀B₁₀ amorphous alloys. These tests confirmed the usability of the developed methodology.

Keywords: magnetoelastic properties, soft magnetic materials
