    Opis:
    In the paper the results of investigation on tensile stresses dependence of magnetoelastic characteristics of cores made of 13CrMo4-5 constructional steel are presented. In the investigation step-cooling test treated samples were used. The step-cooling test process is a type of heat treatment simulating effects of passing time and environmental conditions (temperature and stress) on the sample. In the paper the method of testing the influence of stresses on the magnetic characteristics is presented. Frame shaped samples ensured a closed magnetic circuit and homogeneous distribution of stress. It was found that step-cooling test does not significantly influence the magnetoelastic characteristics and the structure of the samples. On the other hand, then tensile stresses significantly change the magnetic characteristics of 13CrMo4-5 constructional steel. That confirms the possibility of using measurements based on the magnetoelastic effect in the stress assessment for industrial non destructing testing of steel constructions.

    Opis:
    The following paper presents original results of study on the magnetoelastic properties of Ni-Zn (nickel-zinc) ferrite material under low magnetizing fields, corresponding to the so-called Rayleigh region. The investigated $Ni_{0.36}Zn_{0.64}Fe_2O_4$ material was formed into frame-shape sample allowing to obtain uniform stress distribution. Special digitally controlled measurement system was utilized to perform investigation. Obtained results are presented in the paper. On the basis of them mathematical description of magnetoelastic effect in investigated material was developed as an extend of the Rayleigh model of magnetic hysteresis. Comparison of the experimental and modeling results indicates that the developed model is correct.

    Opis:
    The following paper presents the results of investigation on the magnetoelastic Villari effect in structural steel magnetized in the so-called Rayleigh region, which corresponds to relatively low magnetizing fields, much lower than coercive field. Two grades of structural steel were investigated during the performed measurements. Obtained results indicate significant correlation between applied mechanical stress and magnetic properties of the investigated materials.

    Opis:
    The following paper presents the original results of investigation on the magnetoelastic properties of ferrite materials magnetized in low field region, which could be utilized in development of force and stress sensors. The objects of investigation were two ferrite materials (manganese-zinc Mn-Zn and nickel-zinc Ni-Zn). The magnetoelastic characteristics of the materials were investigated with the special measurement system, allowing measurement of magnetic parameters of the ferrite materials magnetized with low fields under the influence of the compressive stress. The obtained results indicate that there is a strong correlation between the magnetic properties of the material in low magnetizing field region, and applied mechanical stress, which allows development of the magnetoelastic stress or force sensor with ferrite core working in low magnetizing field region.

    Opis:
    The following paper presents the basis of a Rayleigh magnetic hysteresis model and the examples of its application for modeling the magnetic characteristics of ferromagnetic materials: ferrites and steels. The presented model allows one to simulate the shape of a magnetic hysteresis loop of the material for the given value of the magnetizing field in the so-called Rayleigh region, as well as to calculate basic magnetic parameters of the material like coercive field, magnetic remanence, and power loss. Four different ferromagnetic materials (two ferrites and two alloy steels) were chosen for the investigation. Each material was investigated within the range of low magnetizing fields, corresponding to the Rayleigh region. On the basis of obtained results, modeling of magnetic characteristics of the investigated materials was performed. Moreover, the range of magnetizing field where the Rayleigh model can be applied for these materials was investigated based on correlation coefficient between experimental results and modeling.
